Two identical charged conducting spheres A and B have their centres separated by a certain distance. Charge on each sphere is and the force of repulsion between them is . A third identical uncharged conducting sphere is brought in contact with sphere A first and then with B and finally removed from both. New force of repulsion between spheres A and B (Radii of A and B are negligible compared to the distance of separation so that for calculating force between them they can be considered as point charges) is best given as:
- A.
- B.
- C.
- D.
