Questions
1. What charge and polarity (what sign) are the two Charge Producers? Where did the electrons go (or come from)?
2. After the rubbing process, what is the overall net charge of the two wands?
3. What evidence is there that the rubbing gave each wand an electrical charge?
4. After charging by contact, what was the charge of the white charge producer and the basket? Was it the same polarity?
5. After charging by contact, what was the charge of the dark charge producer and the basket? Was it the same polarity?
6. After charging by induction, what was the charge of the white charge producer and the basket? Was it the same polarity?
7. After charging by induction, what was the charge of the dark charge producer and the basket? Was it the same polarity?
8. How does the process of charging by contact differ from the process of charging by induction?
9. How many electrons are inside of the pail if the pail has a charge of 50 μC?
10. Assuming you have 6.24 x 1014 electrons and the surface area of the pail is 0.2 m2, what is the charge density (C/m2)?
11. Previously experiments were conducted where two pith balls were used to look at static electricity. Looking at one pith ball as an example, shown below, show the mathematical proof that in this equation the sin can be replaced with a tan.
Fc = mg sin β≡ mg tan β = mgx/l
