1. The problem statement, all variables and given/known data Two charged metallic spheres of same size repel each other by a force F. They are now touched with each other and are then separated to same initial distance. Now the force of repulsion is F'. 2. Relevant equations On touching the spheres will reduce their charges... So the new force of repulsion should be less than the original one... Which is the case but there is also one more case in which the new force F' is greater than original force F. How is that possible? 3. The attempt at a solution Okay so I got the first part correct that F' may be less than F. But I'm stuck here.. How can F' be possibly be larger than F? When the charges do get distributed on touching.. Any help will be appreciated.
