Answer:

3.

a. Electrons do not move between the cans and the charged object. Whatever charge the balloon had before the induction process began is the charge it will have afterwards. The balloon is simply used to induce a movement of charge within the object which is being charged.

b. Two neutral conducting pop cans are touching each other. A negatively charged balloon is brought near one of the cans. The cans are separated while the balloon is nearby. After the balloon is removed the cans are charged.

c. The balloon was then filled with static electricity. When you held the negatively charged balloon close to the soda can, it attracted the positively charged protons in the aluminum.

d. no

e. When the cans are separated, they each have an excess of opposite charge. But when they are brought back together again with the balloon no longer nearby, there is an attraction between this excess of charge. This causes another movement of electrons back to the original neutral state.

f. soda can B
