1. When a rubber balloon is rubbed with fur, the fur loses approximately one billion (10⁹) molecules. Each molecule has a net charge of -e. So, in the electric world, each molecule behaves like an electron. They are electrically equivalent. Assume both the fur and balloon start neutral. (a) What is the net charge on the fur? The sign is important. (b) The billion molecules are not "lost" but are deposited on the balloon. What is the net charge on the balloon? The sign is important. (c) Would you expect the fur and rubber to attract, repel, or do neither?

A common demonstration involves charging a rubber balloon, which is an insulator, by rubbing it on your hair and then touching the balloon to a ceiling or wall, which is also an insulator. Because of the electrical attraction between the charged balloon and the neutral wall, the balloon sticks to the wall. Imagine now that we have two infinitely large, flat sheets of insulating material. One is charged, and the other is neutral. If these sheets are brought into contact, does an attractive force exist between them as there was for the balloon and the wall?
