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.
