Two electrically charged particles, having charges of different magnitude, when placed at a distance 'd' from each other, experience a force of attraction 'F'. These two particles are put in contact and again placed at the same distance from each other. What is the nature of new force between them? Is the magnitude of the force of interaction between them now more or less than F?                

Answer:

                When the two particles are put in contact, they share the difference of charge identically. Hence the two particles repel, with a force less than F.
