Question

Two identical metallic spheres
having charges + 4q and -2q are placed with
their centres 'r dis-tance apart. Force of
attraction between the spheres is F. If the
two spheres are brought in contact and then
placed at the same distance 'r apart, the
force between them:

Answer 1

Answer:

The potential force to pull them apart after having them near is higher but the force after it is brought back to the same distance as it was originally should be virtually the same.

If two charged particles come in contact then the charges are redistributed. If they are positive and negative charged ones, they will be neutralized.
