What happens when like charges interact with each other?

When like charges interact with each other, they repel each other. This behavior is a fundamental principle of electrostatics, which states that charges of the same type (either positive or negative) exert a force that pushes them away from each other. This repulsive force is a result of the electric field created by each charge, which interacts in a way that causes them to move apart.

In contrast, opposite charges attract each other, which is why the attraction or repulsion between charges is a key concept in understanding electrostatic interactions. The notion of charges having no effect upon each other or neutralizing each other does not apply when dealing with like charges, as the fundamental property of their interaction is the force of repulsion. Therefore, the correct understanding of how like charges behave is essential for grasping the basics of electric forces and fields in physics.
