You touch a metal sphere which is positively charged. Which of the following is a correct description of what happens next? (Select all options that you think are correct)
| 1. As opposite charges attract and your body is a reasonably good conductor, some negative charge (if mobile) from your body is attracted to the metal and reduces the net positive charge on the metal. In the process you acquire positive charge. | |
| 2. As like charges repel and your body is a reasonably good conductor, the positive charge (if mobile) tries to spread as far as possible to avoid repulsion. In the end it spreads over you such that net positive charge on the metal sphere is reduced. | |
| 3. As like charges repel and your body is a reasonably good conductor, the positive charge on the metal repels the positive charge from the region of contact in your body. As a result the region of contact becomes negatively charged and the far end of your body becomes positively charged. | |
| 4. As opposite charges attract and your body is a reasonably good conductor, the positive charge on the metal attracts negative charge from your body to the region of contact. As a result the region of contact becomes negatively charged and the far end of your body becomes positively charged. |

At one time it was thought that electric charge was a weightless fluid. An excess of this fluid resulted in a positive charge; a deficiency resulted in a negative charge. Describe at least one experiment for which this hypothesis provides a satisfactory explanation. Check all that apply. Check all that apply.

2. A positively charged object is placed close to a conducting object attached to an insulating glass pedestal (a). After the opposite side of the conductor is grounded for a short time interval (b), the conductor becomes negatively charged (c). Based on this information, we can conclude that within the conductor A. both positive and negative charges move freely. B. only negative charges move freely. C. only positive charges move freely. D. We can't really conclude anything.
