Question

Explainwhy a charged balloon is repelled by another charged balloon whereasan uncharged balloon is attracted by another charged balloon?

Answer 1

Thenature of charges present on the surface of chargedballoons are similar. Since like charges repel each other, twocharged balloons repel each other. When a charged body is broughtnear an uncharged body, the uncharged body acquires charges on itssurface caused by the induction of charges. The charges are ofopposite nature in relation to the charged body. Since unlike chargesattract each other, a charged body always attracts an uncharged body.Hence, an uncharged balloon is attracted by another charged balloon.
