Explain why, a charged balloon is repelled by another charged balloon whereas an uncharged balloon is attracted by a charged balloon. (NCERT Book Question)

There are two types of charges: Positive charge and negative charge. Like charges repel each other and unlike charges attract each other. A charged balloon repels another charged balloon because like charges repel each other. A charged balloon attracts an uncharged balloon by the process of electric induction. The charged balloon produces opposite charges in the nearer end of the uncharged balloon.
