Explanation:
Detailed explanation-1: -(a) If both q1 and q2 are positive, the electrostatic force between these will be repulsive. However, if one of these charges is positive and is greater than the other negative charge, the electrostatic force between them will be attractive. Thus, the nature of force between them can be repulsive or attractive.
Detailed explanation-2: -Opposite charges attract each other, while like charges repulse each other. When two negatively charged objects are brought near each other, a repulsive force is produced. When two positively charged objects are brought near each other, a similar repulsive force is produced.
