Sir test charge can be any value of a very small magnitude or it's magnitude is taken exactly 1 only because in many books it is written UNIT positive charge.

Sir u told that strength of electric field is equal to MAGNITUDE of force, then how come it become a vector.

WHY CANT'T WE USE VERY SMALL NEGATIVE CHARE AS TEST CHARGE?

7 years ago by Pranav Dabhade

Ans 1 ->

If the source charge is positive it'll get attracted to the negative charge

7 years ago by Yukti Khosla

Ans 2 ->

We can, but by convention, to define the direction of electric field absolute, we consider a very small positive test charge

two charges 50microcoulombs and 100micro coulombs are seperated by 0.6m.then how to calculate the intensity of electric field at a point midway between them? and how to calculate the same in case of unlike charges?

8 years ago by archana sabbarapu

Ans 1 ->

Use the result of electric field by point charges and find the vector sum of the two electric field results due to the two charges at the mid point... in case of same polarity charges, it will be subtracted and for opposite polarity charges it will be added...

Respected sir in the first video you had told that electric charges is quantised (they can be integral multiple only and expressed as N*q) so my question is how can the charge be tending to zero ?

8 years ago by Amogh Varsha

Ans 1 ->

1g H consists of 1mole=2.023x10^23 atoms Means 2.023x10^23 electrons. If all were ionised Net charge = no of electrons x charge on 1 electron. So here sir is trying to say Charge tends to zero means reducing the no of electrons.Charge is still quantised.
