Which law states that like charges repel and opposite charges attract?

The law that states that like charges repel and opposite charges attract is known as the Law of electric charges. This fundamental principle in electrostatics describes the behavior of charged particles. Specifically, it tells us that when two objects carry the same type of electric charge (either positive or negative), they will push away from each other. Conversely, when one object has a positive charge and the other has a negative charge, they will pull towards each other. This principle is essential in explaining various phenomena, such as static electricity and the interactions between particles at the atomic and molecular levels.

Other laws mentioned, such as the Law of conservation of charge, focus on the principle that electric charge cannot be created or destroyed, only transferred. Ohm's law relates to the relationship between voltage, current, and resistance in electrical circuits, while Coulomb's law quantifies the force between two charged objects but does not explicitly state the attractive or repulsive nature in such simple terms.
