Dominick Magofna 09/15/2016 NS101-02 Mrs. Liban QFT Chapter 6 1. Explain why a balloon that has been rubbed sticks to a wall for a while. a. The balloon becomes charged from being rubbed. When the balloon is brought near a wall, the charge on the balloon moves electrons around in the wall. What happens next is a small region near the balloon has a charge of the opposite sign than the balloon. The wall is electrically neutral. Now, there are small regions that have charges. The force from the opposite signed charges in the balloon and the wall causes the balloon to stick to the wall. It stays until the charge is gone. 2. Explain what is happening when you walk across a carpet and receive shock when you touch a metal object. a. Excess charge is building up on your body from the carpet as you walk across it. When a metal object is touched, the charge flows out of your body, through the lower resistance of the metal. It finds a path into the ground, which supplied the charge to make up for what you removed from the carpet. 3. Why does a positively or negatively charged object have multiples of the fundamental charge?
