Question:

Read the passage and answer the question.

Two spherical conductors A and B having equal radii and carrying equal charges in them repel each other with a force F, when kept apart at some distance. A third spherical conductor P having the same radius as that of A (or B) but uncharged, is brought in contact with A and then removed away from both.

What is the new force of repulsion between A and B ?

Options:

F/2

F/4

3F/8

3F/16

Correct Answer:

F/2

Explanation:

As the charge on A gets halved, the force gets halved too.
