Question 8

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

Answer

The repulsion between two charged balloons occurs because both balloons carry the same type of charge, resulting in like charges repelling each other. On the other hand, when a charged balloon is brought close to an uncharged balloon, due to induction, the uncharged balloon acquires opposite charge. Due to this they are attracted to each other.
