A class does a science experiment. They rub a balloon with a piece of wool. They put the balloon close to a penny and pleces of tissue paper. They find that the tissue paper moved toward the balloon and the penny did not
What caused the tissue paper to move towards the balloon?

D. Electrical charge

Explanation:

What actually caused the tissue paper to move towards the balloon is "electrical charge".

When they rubbed the balloon with a piece of wool, the wool looses electrons which gives it a positive charge while the balloon gains electrons which gives it a negative charge.

The pieces of tissue paper is able to move toward (i.e attracted) the balloon because the negatively charged balloon is attracted to the positively charged tissue paper which was neutral.
