Two small spheres have the same mass and volume. One of the spheres has a charge of 4.00 pl: and the other sphere has a charge of -1.00 pt. If these two spheres are brought Into brief contact with each other and then separated to a distance of 2.00 x 10'1 m, what is the electric force between them at this distance? [5.06 x 10'1 N]
