Why Charged Ballon Getting Repelled
Explain why a charged balloon is repelled
by another charged balloon whereas an
uncharged balloon is attracted by another charged balloon?
The charged balloons have similar charges on the surfaces. Since like charges repel each other, that's why the charged balloon is repelled by another charged balloon. When an uncharged
balloon is brought near a charged one, the uncharged balloon acquires some opposite charge.
Since unlike charges attract each other, therefore a charged balloon attracts an uncharged one.
