Electrostatics questions

1. What is the difference between an electron and a proton: in terms of charge? In terms of mass? In terms of position in an atom?

2. By "charging" something, what is usually happening? If the object is becoming negatively charged? Positively charged?

3. What is the charge of a proton? An electron?

4. Knowing the charge of one proton, how many protons would be required to make one coulomb of charge? This will be a large number.

5. Explain the rotating meter stick demonstration (similar to how a balloon sticks to a wall).

6. What is a Van de Graaff generator?

7. What is "grounding?"

8. What do you suppose occurs when lightning strikes?

9. What happens to the electrostatic force between two charged objects if the distance between them is doubled? Tripled? Halved?

10. What do we mean by "fundamental" charge? What charges are fundamental?
