Question

Why do two charge bodies attract or repel ?​

Answer 1

Explanation:

When the two bodies have the same charges, they repel each other and when the two bodies have different charges they attract each other.

Answer 2

In contrast to the attractive force between two objects with opposite charges, two objects that are of like charge will repel each other. That is, a positively charged object will exert a repulsive force upon a second positively charged object. This repulsive force will push the two objects apart.
