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 on each is is 6.5 into 10 raise to power minus 7 coulomb the radius of the radius of A and B are negligible compared to the distance of separation what is the force of repulsion if each sphere is charged double the above amount and the distance between them is half?
