a plastic rod becomes negatively charged when it is rubbed with a piece of wool. how does the rod become charged?\nelectrons move from the rod to the wool.\nprotons move from the rod to the wool.\nelectrons move from the wool to the rod.\nprotons move from the wool to the rod.

Answer

Brief Explanations:

Charging by friction occurs when electrons are transferred. Protons are bound in the nucleus and don't move during such processes. Since the rod becomes negatively - charged, it gains electrons. So electrons move from the wool to the rod.

Answer:

Electrons move from the wool to the rod.
