The electric force on a charge `q_1` due to `q_2` is `(4hati-3hatj)N`. What is the force on `q_2` due to `q_1`

Electric force between two point charges q_(1) and q_(2) at rest is F. Now is a charge -q_(1) is placed next to q_(1) . What will be the (a) force on q_(2) due to q_(1) (b) total force on q_(2) ?

The electric lines of force of two point charges are shown in fig. What is the value of the ratio q_(1)//q_(2) ?

A charge q_1 exerts some force on a second charge q_2 . If third charge q_3 is brought near charge q_1 , the force of q_1 exerted on q_2

Given two point charges q1 and q2 , such that q1q2<0. What is the nature of force between them?

The electric potential enegy U of the system of charges q_1 and q_2 is
