1) When you rub the ebonite with wool (or fur) or the glass rod with silk, the rod becomes charged by a process called?

2) When you touch the ebonite or glass rod to the neutral electroscope the electroscope becomes charged by the process called what?

3) When you touched the charged electroscope with your finger, the leaves converged ("collapsed") by a process called?

4) When you brought a charged rod near the neutral electroscope, the leaves diverged by a process called what?

5) You come across a charged electroscope, but you don't know whether it is charged positively or negatively.Describe a test you would perform to determine which way it is charged. Include the results of your test(s) in your description.

6) Explain, using the movement of electrons, what happens to the leaves of an electroscope as an ebonite rod that has been rubbed with wool (or fur) is (a) brought near a neutral electroscope, and then (b) is touched to the head of the electroscope.

7) Why do the leaves of a charged electroscope collapse when you touch it no matter which way it was charged? Use the movement of electrons in your answer.

8) If you charge an electroscope by permanent induction using a negative rod, what charge results on the electroscope?

9) If you charge an electroscope by permanent induction using a positive rod, what charge results on the electroscope?
