A Small Story About Electric Field Intensity
One day, a student from Salt Lake City asked Kumar Sir:
“Sir, whenever questions come from Electric Field Intensity, I get confused. How do we know the direction of electric field?”
Kumar Sir smiled and said:
“Physics becomes easy when you imagine things properly.”
Then he drew two charged plates on the board.
He said:
“Suppose we have two charged sheets or plates. Now we want to find the electric field intensity at different points.”
He marked three points:
Point A
Point B
Point C
Then Kumar Sir said something very important:
Whenever we try to find electric field intensity at any point, we imagine placing a UNIT POSITIVE CHARGE at that point.
This is one of the most important properties of electric field.
What Happens When We Place a Unit Positive Charge?
Imagine a tiny positive charge placed at Point A.
If the nearby plate is positively charged, it will repel the unit positive charge.
If another positive plate is nearby, that will also repel it.
So the unit positive charge experiences force from both sides.
At another point, the directions may change.
At some places, both forces may add.
At some places, both forces may cancel.
This is how we understand electric field intensity.
The Golden Property of Electric Field Intensity
The most important idea is:
To find electric field intensity at any point, we place an imaginary UNIT POSITIVE CHARGE there.
That charge is only imaginary for understanding direction and force.
The direction in which the unit positive charge moves is the direction of electric field.
This is the simplest and strongest concept.
Why Do Students Fear Electrostatics?
Most students directly start solving numerical problems.
They memorize:
E = F/q
Electric field due to sheet
Electric field due to charge
Superposition principle
But they do not understand what is actually happening physically.
Kumar Sir always says:
“If you can imagine Physics, you can solve Physics.”
This is why students from different boards and exams learn faster with Kumar Sir.
A Real Classroom Style Explanation
Suppose two positive sheets are placed parallel to each other.
Now imagine placing a unit positive charge:
Near the left sheet
Between the sheets
Outside the sheets
At every point, the unit positive charge experiences repulsion.
The total electric field depends on vector addition.
This is exactly how advanced questions in:
NEET
IIT JEE
Boards
Olympiads
are solved.
Why Kumar Sir’s Method Is Different
Most coaching centers focus only on speed.
But Kumar Sir focuses on:
Visualization
Concept building
Real understanding
Question variety
Board + competitive preparation together
Students understand not only “what formula to use,” but also “why the formula works.”
That is why many students improve their confidence within a few weeks.
Learning Physics Like a Story
Imagine you are standing between two charged walls.
Now imagine you are a tiny positive charge.
One wall pushes you.
Another wall pushes you too.
Now ask yourself:
Which side force is bigger?
Are both forces equal?
Will you move left?
Will you move right?
Will you remain balanced?
This imagination itself becomes Physics.
This is exactly the teaching style of Kumar Sir.
Physics for Every Type of Student
Some students are weak in basics.
Some students are average.
Some students are already good but want higher ranks.
Kumar Sir teaches according to the level of the student.
Whether you are preparing for:
Medical entrance
Engineering entrance
School boards
International boards
the teaching style is adjusted accordingly.

Why Electric Field Becomes Easy with Proper Visualization
When students imagine a unit positive charge at a point, many confusing things become simple:
Direction of field
Nature of force
Vector addition
Cancellation of fields
Symmetry concepts
This single property helps in solving many advanced problems.
Kumar Sir Teaches Concept + Questions Together
After theory, students solve many varieties of questions:
Conceptual questions
Assertion reasoning
Numerical problems
Previous year questions
NEET questions
IIT level problems
This improves both confidence and speed.

A Student’s Experience
One student once said:
“Earlier I used to fear electrostatics. I could not understand why electric field has direction. But when Kumar Sir explained using imaginary unit positive charge, everything became easy.”
This is the power of proper teaching.
Physics Is Not About Memorization
Physics is about understanding nature.
Electric field is invisible.
So we use a unit positive charge to detect its behavior.
That is why this property is extremely important.
Step-by-Step Thinking Method
Whenever you see electric field questions:
Step 1:
Imagine placing a unit positive charge.
Step 2:
See which charge attracts or repels it.
Step 3:
Find direction of force.
Step 4:
Add all electric fields vectorially.
This simple method solves many difficult problems.

Final Understanding of Electric Field Intensity
Always remember this powerful line:
Whenever we try to find electric field intensity at any point, we imagine placing a UNIT POSITIVE CHARGE there.
Then we observe:
attraction
repulsion
direction of force
and finally determine electric field.
This is the foundation of electrostatics.
