Two negative, equally charged drops of water, 0.80 mm apart, exert an electrostatic force of 78.5 x 10-9 N on each other. Determine the net charge on each drop. Give your answer in the form "a.bc" pico-Coulombs. For the previous problem determine the number of electrons that had been added to each drop to cause the net charge on each drop. Give your answer in the form "ab.c" mega-electrons.
