Two identical small spheres are initially charged and set a certain distance apart where there exists an initial electrostatic force of magnitude F between the two. Gradually over a period of time, the charge in each sphere reduces due to charge leakage, such that the final charge in each is only 1/4 of their initial charge. i.e., qf = (1/4)q. What is the magnitude of the electrostatic force between the two spheres after the reduction of charge? (1/16)F
