Questions 3-4 use the following scenario: A sweater comes fresh out of the drier and you notice that your hair is attracted to it. You decide to run
a couple of experiments on it to determine the charge on the sweater.
3. The sweater repels a negatively charged rubber rod. Which of the following is a fully correct
conclusion you can draw?
a. The Sweater has a negative charge
b. The Sweater has a positive charge
C. The Sweater is neutral
d. The Sweater is either neutral or has a positive charge
4. The Sweater then picks up small slips of paper. Which of the following is a fully correct
conclusion you can draw?
a. The paper has a negative charge
b. The paper has a positive charge
C. The paper is neutral
d. The paper is either neutral or has a positive charge
5. Why do you pick up an electric charge when walking on carpet while wearing socks?
a. Rubbing your feet against the carpet creates electrons on your socks
b. The carpet has a charge already and pushes the electrons in your body away
There is a transfer of protons from the socks rubbing against the carpet
d. There is a transfer of electrons from the socks rubbing against the carpet
C.
