f two objects repel one another, you know they have like charges on them. But how would you determine whether they were both positive or both negative? 2. Suppose that you have an electrically charged stick. If you divide the stick in half, each half will have half the original charge. If you split each of these halves, each piece will have a quarter of the original charge. Can you keep on dividing the charge in this manner forever? If not, why not? 3. You remove two socks from a hot dryer and find that they repel each other with forces of 0.001 N when they're 1 cm apart. If they have equal charges, how much charge does each sock have? 4. A Ping-Pong ball contains an enormous number of electrically charged particles. Why don't two Ping-Pong balls normally exert electrostatic forces on each other? 5. When technicians work with static-sensitive electronics, they try to make as much of their environment electrically conducting as possible. Why does this conductivity diminish the threat of static electricity? 6. How close would you have to bring 1 C of positive charge and 1 C of negative charge for them to exert forces of
