Q
Some Natural Phenomena

Question:

Explain why a charged balloon is repelled by another charged balloon whereas an uncharged balloon is attracted by another charged balloon?

Answer:

A charged balloon repels another charged balloon because the charge on the surface of the same material is the same in nature and like charges repel each other, hence they repel each other. When an uncharged balloon is brought closer to a charged balloon, the uncharged balloon acquires the opposite charge on its surface due to the induction. Thus, both attract each other as unlike charges have the force of attraction between them.
