Assignment – Static Electricity (Ch.10)

1. What are the possible interactions between two charged objects?

2. How do a charged object and a neutral object interact?

3. Explain the role of friction in creating a charged object.

4. Two neutral objects, A and B, were rubbed together, resulting in object A being charged

positively. What is now the charge on B?

a) How do you know?

b) Which object, A or B, is likely higher on the triboelectric series?

c) How do you know?

5. Define electrical discharge.

a) What is a real-life example of an electrical discharge?

6. Describe a device that uses static electric charges. Include a labeled diagram as part of

your answer.

7. Describe a device that protects other devices by controlling static electric charges.

Include a labelled diagram as part of your answer.

8. Explain why a positively charged balloon will stick to a wall just as easily as a

negatively charged balloon.

9. You have an unknown material that becomes charged when you rub it with silk. You

also have a negative ebonite rod and a positive glass rod. How can you determine the

charge of the unknown object?

10. You run a brush through your hair and wonder if it has become statically charged.

Design a test that allows you to determine if the brush has a charge.
