Answer: STATIC FORCE BETWEEN BALLOONS
- When rubbing a balloon with a wool cloth, it puts negative charges on the balloon.
- Negative charges attract to positive charges. If a balloon is not rubbed with the wool cloth, it has an equal amount of negative to positive charges, so it will attract to a rubbed balloon.
- When both balloons are rubbed with the wool cloth, the both receive negative charges, so they will repel each other.
