Premium Physics Practice for Serious NEET Preparation
This assessment is designed for students who want to check their Physics preparation with discipline and honesty. Attempt each question before opening the answer or solution, and treat the paper as a timed online-style practice test.
The paper covers important Class 11 and Class 12 Physics ideas, including mechanics, heat, waves, electricity, magnetism, optics and modern physics. The aim is not only to know the answer, but to understand the reasoning behind it.
Why Strong Physics Preparation Is Now More Important Than Ever
Physics is becoming increasingly decisive for NEET aspirants because it rewards conceptual clarity, numerical discipline and the ability to connect ideas across chapters. Students who depend only on memorised formulas often struggle when the same concept is presented in a new format.
A strong Physics foundation helps you read questions faster, identify the correct principle, avoid calculation traps and manage exam pressure with confidence. Regular practice with properly matched solutions is one of the best ways to build that accuracy.
Use this paper as a diagnostic test. Mark the questions that feel slow, revise the related theory, and then reattempt similar problems until the method becomes natural.

A body is moving down a long inclined plane of inclination θ. The coefficient of friction between the body and inclined plane varies as μ = 0.5x, where x is distance travelled down the plane. The body will have maximum velocity when it has travelled a distance x given by (all quantities are in SI units)
Correct Answer: Option 1
Official Solution
When velocity is maximum, acceleration is zero. So g sinθ - 0.5x g cosθ = 0. Hence x = sinθ/(0.5 cosθ) = 2 tanθ.

A particle of mass m strikes elastically with a disc of same mass with speed v as shown in figure. All surfaces of contact are smooth. The velocity of disc just after collision is (take tangential line as +x-axis and radial line toward C as +y-axis at the point of impact).
Kumar Sir +91 9958461445
Correct Answer: Option 1
Official Solution
Conserve linear momentum along the normal. Since particle and disc have equal mass, momentum is exchanged along the normal. vD = v cosθ ĵ. From the figure sinθ = 1/2, so θ = 30°. Thus vD = (√3/2)v ĵ.
Question 8
Correct +4 | Wrong -1 | Unattempted 0
A pendulum consists of a wooden bob of mass m and a string of length l. A bullet of mass m1 is fired towards the pendulum with velocity v1. The bullet comes out of the bob with speed v1/4 and the bob just completes the vertical circle. The velocity v1 is
Correct Answer: Option 3
Official Solution
Using conservation of linear momentum: m1v1 = m√(5gl) + m1v1/4. Hence (3/4)m1v1 = m√(5gl), so v1 = (4m/3m1)√(5gl).
Question 9

A body of mass M and radius R, rolling on a smooth horizontal surface with velocity v, rolls up an inclined plane up to a vertical height 3v2/4g. The shape of body is
Correct Answer: Option 1
Official Solution
Apply conservation of energy: KT + KR = Mgh. Thus (1/2)Mv2(1 + K2/R2) = (3/4)Mv2, giving K2/R2 = 1/2, which corresponds to a disk.
Question 10
Correct +4 | Wrong -1 | Unattempted 0
The escape velocity from a spherical planet is ve. The escape velocity corresponding to another planet of twice the radius and half the mean density is
Correct Answer: Option 1
Official Solution

A glass beaker having mass 390 g and an interior volume of 500 cm3 floats just submerged in water when it is half filled with water. The density of material of beaker is approximately
Correct Answer: Option 2
Official Solution
Total floating mass = 390 + 250 = 640 g, so outer volume = 640 cm3. Volume of beaker material = 640 - 500 = 140 cm3. Density = 390/140 = 2.8 g/cm3.
Question 12

A ring is cut from a platinum tube of internal diameter 8.5 cm and external diameter 8.7 cm. It is supported horizontally on water surface. If an extra force of 4.0 g wt is required to pull it away from water surface, then surface tension of water is (g = 10 m/s2)
Correct Answer: Option 2
Official Solution
Force due to surface tension F = T(2πr1 + 2πr2). Therefore T = (4 × 10-3 × 10)/(3.14 × (8.5 + 8.7) × 10-2) = 7.4 × 10-2 N/m.
Question 14
Correct +4 | Wrong -1 | Unattempted 0
The temperature of 200 g of water is to be raised from 24°C to 90°C by adding steam at 100°C. The mass of steam required for this purpose is
Correct Answer: Option 2
Official Solution
Heat lost by steam = heat gained by water. m × 540 + m × 1(100 - 90) = 200 × 1(90 - 24). Thus 550m = 13200, so m = 24 g.

If λm denotes the wavelength at which the radiative emission from a black body at temperature T K is maximum, then
0.014 kg of nitrogen is enclosed in a vessel at a temperature of 27°C. The amount of heat transferred to the gas to double the r.m.s. speed of molecules is nearly
Correct Answer: Option 1
Official Solution
The vessel keeps volume constant, so Q = nCvΔT. Since vrms ∝ √T, doubling speed makes T2 = 1200 K from T1 = 300 K. Q = (1/2) × 5 × 2 × 900 = 2250 calorie.
Question 17
Correct +4 | Wrong -1 | Unattempted 0
If 90 cal of heat is required to raise the temperature of 2 mole of an ideal gas at constant pressure from 30°C to 35°C, the degree of freedom of the gas molecule is
Correct Answer: Option 2
Official Solution
ΔW = nRΔT = 2 × 2 × 5 = 20 cal. ΔU = Q - ΔW = 90 - 20 = 70 cal. From γ = Cp/Cv = 9/7 and γ = 1 + 2/f, the degree of freedom f = 7.

21 tuning forks are arranged such that every fork gives 5 beats per second with the next. The last fork has a frequency that is double of the first. Frequency of 11th fork in Hz is
Correct Answer: Option 3
Official Solution
For 21 forks there are 20 intervals. 2n - n = 20 × 5, so n = 100. Therefore n11 = n1 + 10 × 5 = 150 Hz.
Question 21
Correct +4 | Wrong -1 | Unattempted 0
When an oscillator completes 50 oscillations, its amplitude reduces to 1/3 times of the initial value. The amplitude, when it completes 100 oscillations, will be
Correct Answer: Option 2
Official Solution
A = A0e-bt/2m. After 50 oscillations A/A0 = 1/3. After 100 oscillations, the factor is squared: A/A0 = (1/3)2 = 1/9.

A particle having charge equal to that of electron and mass 1.6 × 10-30 kg is projected with initial speed v at an angle of 45° with the lower plate as shown. The plates are sufficiently long and have separation 2 cm. Electric field between the plates is 0.5 × 103 V/m upward. The maximum value of velocity of particle not to hit the upper plate is
Kumar Sir +91 9958461445
Correct Answer: Option 2
Official Solution
For the particle just not to hit the upper plate, vy becomes zero at the upper plate. Use v2 = u2 + 2as: 0 = (u/√2)2 - 2(qE/m)(2 × 10-2). This gives u2 = 4 × 1012 and u = 2 × 106 m/s.

In the given circuit diagram E = 5 V, r = 1 Ω, R1 = R3 = 1 Ω, R2 = 4 Ω and C = 3 μF. The numerical value of charge on each capacitor is
Kumar Sir +91 9958461445
Correct Answer: Option 3
Official Solution
Current i = E/(R2 + r) = 5/(4 + 1) = 1 A. Terminal voltage V = E - ir = 5 - 1 = 4 V. Effective capacitance is 1.5 μF, so q = CeffV = 1.5 × 4 = 6 μC.
Question 24
Correct +4 | Wrong -1 | Unattempted 0
The capacitance of capacitor of plate area A1 and A2 (A1 < A2) at a distance d as shown in the figures is
Kumar Sir +91 9958461445
Correct Answer: Option 2
Official Solution
Only the overlapping effective plate area contributes. Since A1 < A2, effective area = A1. Hence C = ε0A1/d.
Question 25
Correct +4 | Wrong -1 | Unattempted 0
As the switch S is closed in the circuit shown in figure, the current passed through point A is
Kumar Sir +91 9958461445
Correct Answer: Option 1
Official Solution
Applying KVL in POQ: 20 - 2i - 4(i - i1) = 5, so 6i - 4i1 = 15. Applying KVL in POE: 20 - 2i - 2i1 = 0, so i + i1 = 10. Solving gives i1 = 4.5 A.
Question 26

Resistance of a conductor at temperature t°C is R = R0(1 + at + bt2). Here R0 is resistance at 0°C. The temperature coefficient of resistance at temperature t°C is
Correct Answer: Option 1
Official Solution
Temperature coefficient α = (1/R)(dR/dt). With R = R0(1 + at + bt2), dR/dt = R0(a + 2bt). Hence α = (a + 2bt)/(1 + at + bt2).
Question 27
Correct +4 | Wrong -1 | Unattempted 0
A potentiometer wire, 10 m long, has a resistance of 40 Ω. It is connected in series with a resistance box and a 2 V storage cell. If the potential gradient along the wire is 0.1 mV/cm, the resistance unplugged in the box is
Correct Answer: Option 2
Official Solution
Potential gradient K = 0.1 × 10-3/10-2 = 0.01 V/m. Since K = i(R/L), 0.01 = 4i, so i = 0.25 × 10-2 A. Also i = 2/(40 + R). Hence 40 + R = 800 and R = 760 Ω.
Question 28
Correct +4 | Wrong -1 | Unattempted 0
If E denotes electric field in a uniform conductor and vd the drift velocity of free electrons in the conductor, then which of the following graph is correct?
Correct Answer: Option 1

A conducting circular loop of same material is placed as shown in figure. The area of cross section of part APC is A and of AQC is A/3. The magnetic field at centre O is
Kumar Sir +91 9958461445
Correct Answer: Option 1
Official Solution
The resistances of the two paths become equal, so current divides equally: i1 = i2 = i/2. The magnetic fields due to the two arcs are opposite and unequal, giving net B = μ0i/8R.
Question 30
Correct +4 | Wrong -1 | Unattempted 0
An electron and proton having same kinetic energy enter into a magnetic field perpendicular to it, then
Correct Answer: Option 2
Official Solution
Radius of path r = √(2Km)/(qB), so r ∝ √m for equal kinetic energy and equal magnitude of charge. Proton has greater mass, hence larger radius and less curved path.

Figure shows a square current carrying loop ABCD of side 2 m and current 1/2 A. The magnetic moment M of the loop is
Kumar Sir +91 9958461445
Correct Answer: Option 1
Official Solution
Magnetic moment M = iA vector. From the loop geometry, M = (1/2)[4cos60° î - 4sin60° k̂] = (î - √3 k̂) A m2.
Question 32
Correct +4 | Wrong -1 | Unattempted 0
An ammeter is obtained by shunting a 30 Ω galvanometer with a 30 Ω resistance. The additional shunt required to double the range is
Correct Answer: Option 1
Official Solution
Initially, the 30 Ω galvanometer and 30 Ω shunt share current equally. For double range, (2i - i/2)S = (i/2) × 30, so S = 10 Ω. Since 10 Ω is made by 30 Ω in parallel with additional shunt S', 1/10 = 1/30 + 1/S', giving S' = 15 Ω.

The rod is released from horizontal position. The potential difference between the two ends of rod when rod makes an angle θ with horizontal is proportional to
Correct Answer: Option 4
Official Solution
Loss of potential energy equals gain in rotational kinetic energy: mgl sinθ = (1/2)Iω2. This gives ω ∝ √(sinθ). Motional emf ΔV = (1/2)Bωl2, so ΔV ∝ (sinθ)1/2.
Question 35
Correct +4 | Wrong -1 | Unattempted 0
A capacitor, an inductor and an electric bulb are connected in series to an AC supply of variable frequency. As the frequency of supply is increased gradually, the electric bulb is found to be
Correct Answer: Option 3
