Question: When separated by distance d, identically charged objects A and B exert a force of magnitude F on each other. If you reduce the charge

When separated by distance d, identically charged objects A and B exert a force of magnitude F on each other. If you reduce the charge of A to one-forth its original value, and the charge of B to one-fifth, and reduce the distance between the objects by half, what will be the ratio of the new force F? that they exert on each other to previous force F?
