A student is investigating the distribution of charge in a conductor, He attaches two unopened soda cans on their sides to two foam cups with tape. He sets the soda cans with the cups onto a tabletop so that they are touching one another. Then he moves a negatively charged balloon close to the left soda can. The set up for the investigation is shown
How do the electrons move in the soda cans?
A. They move to the top of both cans
B. They move to the bottom in both cans
C. They move from the right can to the left can
D. They move from the left can to the right can
C. They move from the right can to the left can
When the negatively charged balloon is brought close to the left soda can, it induces a positive charge on the right soda can, causing electrons to move from the right can to the left can in response to the repulsion of the negative charges.
