1. When you rub a balloon in your hair, the balloon picks up about an excess charge of about -1/C (that's -1 x 10-6C). Imagine you charge up a second balloon with your hair, giving it the same charge as the first balloon. (a) 2 points. If you hold the balloons about 1 cm (that's 0.01m) apart, what force will they exert on each other, in Newtons? (b) 2 points. Is the force in (a) an attraction or repulsion? How do you know? (c) 2pts. If the net charge on each balloon is -1UC, how many electrons were transferred to each
