Two identical charged metallic spheres are separated by 3 3 com has attractive electrostatic force between them. They are made to touch each other and seperated to 3,3 crn distance again. As a resun the force tuma to repuhive and 10 times smaller in magnitude than the carber attractive force if 70 micro C charge is exchanged during this process, find the magnitude of charge (n micro C) loft in each sphere at the end
