Answer 2

Not all charges repel each other. If two charges having same polarity when brought towards each other there exist a repulsive force btw them ie, when two positively charged objects are brought together a positively charged object will exert a repulsive force upon a second positively charged object. This repulsive force will push the two objects apart.

In the similar way when two charges having opposite polarity when brought towards each other there exist a attractive force btw them ie, when one positively charged object and another negatively charged object are brought together then either of the positively charged object or negatively charged object will exert a attractive force upon a second charged object. This attractive force will push the two objects close by.

So, like charges repel each other and unlike charges attract each other.
