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 P ?

F/4

The charge on each of the A and P is half the original charge. So the force gets reduced by a factor of 4.
