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

A.VERIFIED ANSWERfact-checked by tutors

Soln:

The surface charge on the balloons is of the same nature; hence, they get repelled. When a charged balloon is brought near an uncharged balloon due to the induction of charges, it acquires charges which are opposite in nature to that of a charged balloon. As unlike charges attract each other, the uncharged balloon gets attracted by the charged balloon.
