Question

when 2 electrically charged particles having charges of different magnitudes, kept at d distance from each other, they experience a force of attraction F. these 2 particles are put in contact and again placed at same distance from each other. what is nature of new force between them. explain.

Solution

When they come in the contact , charge will be uniformly distributed on both the spheres.

So net force between them will increase.
