1) what is the e lectric force between a glass ball that has +3.9 mC of charge and a rubber ball that has -5.0mC of charge and a rubber ball that has -5.0 mC of charge when they are separated by a distance of 3.5 cm? The Coulomb constant is 8.98755 x 10^9 N*m(sq)/C(sq). Answer in N.
2) Two electrons in an atom are separated by 1.5 x 10^ -10 m, the typical size of an atom. The Coulomb constant is 9 x 10^9 N*m(sq)/C(sq). What is the force between them? Answer in N.
3) Would you feel any electrical effects if you were inside the charged sphere of a van de Graaff generator? Why or why not?

I'll take on item 3. The answer is no. You are in an equi-potiential environment and there is no path across which a potential difference can occur. To get a zap, you need a circuit that closes between the ball and the other end of the generator with you as a part of it.
