You electrically charge a plastic rod by rubbing it against fur. You then place the rod near a few little pieces of paper and the pieces of paper stick to the plastic rod. Explain why this happens. Think of what happens to the charge inside of the pieces of paper. The charged rod transfers electrons to the pieces of paper, creating charge unbalance. The excess negative charge on the plastic rod attracts the negative charges in the pieces of paper, causing charge polarization. The charged fur transfers electrons to the pieces of paper, creating charge unbalance. The charged paper transfers electrons to the rod, creating charge unbalance. The charged rod transfers protons to the pieces of paper, creating charge polarization. The paper is a naturally charged object so it is attracted by the plastic rod. It is impossible to determine because we don't know the amount of charge on each.
