Question

{a}. Two insulated charged copper spheres A and B have their centres separated by a distance of 50 cm.
what is the mutual force of electrostatic repulsion if the charge of each is 6.5 into 10^-7 C?
the radii of A and B are negligible compared to the distance of separation.


{b}. what is the force of repulsion if each sphere is charged double the above amount, and the distance between them is Halved?
