Question

Two charges of same magnitude and at distance r exerts a force of f on each other. If charge are halved and distance between them is double the new force acting on each charge is

Answer 1

Explanation:

If the charges are halved and the distance between them is doubled the electric force becomes (1/16)th times that of initial force. New electric force is given by : So, if the charges are halved and the distance between them is doubled the electric force becomes (1/16)th times that of initial force.
