The force of interaction between two charges

{q_1} = 6\mu \;

C and

{q_2} = 2\mu

C is 12 N. If charge

q = - 2\mu

C is added to each of the charges, then the new force of interaction is

View answer and explanation

Correct option: B

Zero

Option B (Zero) is correct because adding the same charge to both original charges results in the product of the new charges being zero, thus the force is zero.

Assertion:- Electric field lines do not cut at any point.
Reason:- At any point, there is only one direction of electric field. Statement-I: A positive point charge is brought in an electric field, the electric field at neary by point will increase

Statement-II: Electric field produced by charge may favour the existing electric filed Two particles having equal mass and charge
