Question
Place the can on top of the styrofoam pad. Rub the rod vigorously with the fur for several seconds. Next rub the rod on the inside of the can several times to transfer charge to it. Repeat this entire procedure at least five times to transfer a significant charge. Bring the aluminum-covered ball hanging from the string close to but not touching the outside of the can. What happens when the ball is brought close to the can? Now touch the ball to the outside of the can, and then move it a very short distance away. What happens after the ball is touched to the side of the can and then moved away? What seems to have happened to the charge you put on the inside of the can? Explain based on your observations.
Explanation / Answer
All elements in nature have a neutral electrical state, that is, have equal amount of electrons and protons. In electrostatics, there are methods with which charge or discharge a metal, these are three mainly: contact charging, charge by rubbing and inductive charging. If you rub both the can and the ball and approach each other, they stay away because both are charged equally (equal sign repel), however, if the ball comes into contact with the can will discharge and either no effect was observed until entices charge again in metals. I advice you to read about this methods and the electrostatic. I hope that could help you, Regards!
