Electrostatic repulsion is the force between two charges having the same sign, that tends to separate them further. The force is proportional to the product of the charges, and inversely proportional to the square of the distance between them.
Electrostatic repulsion is when 2 like charges repel each other. Simple as that!
Electrostatic repulsion is the force that occurs between two like charges, pushing them away from each other. It follows Coulomb's law, which quantifies this force based on the charges and the distance between them. A common example is when two positively charged balloons repel each other when brought close together.
