Question

A balloon that has been rubbed on wool has a negative charge. When the balloon is held over—but not touching—some bits of paper, some of the bits jump up to the balloon. Why does the paper move?

Answer 1

This process is known as static electricity

Step-by-step explanation:

When balloon is rubbed on the wool , a negative charge is usually formed. When the balloon is then held over—but not touching—some bits of paper, some of the bits jump up to the balloon. The bits which jump up to the balloon are positive charged and we know that unlike charges attract.

This process explains static electricity which is when the charges on a material are not in a balanced state.
