1) Assume that you are way out in space, very very far away from other masses, and you have two identical particles each of which has the charge of a electron. Suppose you hold both of these particles 0.1m apart from each other and then release them. What mass would these particles have to have in order for the gravitational force to exactly balance the electric force? (So that they don't move.)
