Question

Explain why a charged balloon is repelled by another similarly charged balloon whereas an uncharged balloon is attracted by another charged balloon? [5 MARKS]

Answer 1

Each point: 1 Mark

1. The nature of charges present on the surface of charged balloons are similar.
2. As we know that like charges repel each other, two charged balloons repel each other.
3. When a charged body is brought near an uncharged body, the uncharged body acquires charges and the charges are of opposite nature with respect to the charged body.
4. Since unlike charges attract each other, a charged body always attracts an uncharged body.
5. Hence, an uncharged balloon is attracted by another charged balloon.
