What would be the interaction force between two copper spheres each of mass 1 g, separated by distance 1 m, if the total electronic charge in them differed from the total charge of the nuclei by one percent.?
Two charged spheres A and B charged with the charges of + 10 and +20 coulombs respectively and Separated by a distance of 80 cm. The electric field at a point on the line joining the centres of the two spheres will be zero at a distance from sphere A
