What happens to the electrical charges of the same sign when they are brought close together?

When electrical charges of the same sign are brought close together, they repel each other. This is a fundamental principle of electrostatics, which states that like charges repel and opposite charges attract. The repulsive force occurs because both charges create electric fields that exert a force on each other, pushing them apart.

This repulsion is a result of the fundamental properties of electric charge and is consistently observed in various scenarios involving charged particles. For instance, if two positive charges or two negative charges are inserted into a controlled environment, they will move away from each other due to this repulsive interaction. Understanding this behavior is crucial in fields like physics and engineering, where controlling and manipulating electric charges are essential for designing circuits and other electronic components.
