Question

No need to fully answer each question but could someone please give me a brief run down of what is supposed to happen in all three of those scenarios?

Wad a small amount of aluminum foil into a ball about 3 cm in diameter and suspend it from a piece of thread about 30 cm long. 1. Tape the loose end of the thread to a support so that the ball hangs freely at a reachable height which is at least 15 cm above any surface and 30 cm from any side obstructions. a. Neutralize the ball by touching it with your finger and then charge a plastic ruler by rubbing it with fur. b. Steady the ball, and then bring the charged ruler close to but NOT TOUCHING the ball. If the ball accidentally touches the ruler, neutralize the ball and try again. C. Describe what you observed. Why does this happen? Use appropriate diagrams to help you explair. d. 2. Neutralize and steady the aluminum foil ball a. Charge the plastic ruler and again bring it close to but NOT TOUCHING the ball. Then gently and quickly touch the ball with your finger on the side opposite the ruler b. Now bring the charged ruler very close, but still NOT TOUCHING the ball and observe for a few seconds. What do you observe? What does this observation mean in terms of the charge on the ball and the ruler? Exactly what was the purpose of touching the ball while the ruler was nearby? Draw appropriate diagrams to support your verbal descriptions. You should draw more c. d. e. than one illustrative diagram for this section. 3. Neutralize the aluminum foil ball. Bring the charged ruler close enough to the ball so that the ball gently and quickly touches it only once. Describe what you observe just after they touch. Explain why this happens in both words and appropriate diagrams.
