g Explain why the foil is attracted at first by the charged rod. Consider any charge that exists in the uncharged foil. (You will consider later interaction between the rod and foil in the last question. Just think about the first interaction when answering this question.) [4] (Hint: It might help to recall that aluminum is a metal so charge in it can move. You will have to think about the interaction between any charge that has separated in the aluminum and the charge on the charged rod.)
