What does Coulomb's Law describe?

Coulomb's Law fundamentally describes the relationship between two charged objects, quantifying the force exerted between them based on their charges and the distance separating them. This law states that the magnitude of the electrostatic force between two point charges is directly proportional to the product of the absolute values of the charges and inversely proportional to the square of the distance between them. In essence, this law captures the interaction between electrically charged particles, which can either attract or repel depending on the nature of the charges (like charges repel, while opposite charges attract). Understanding Coulomb's Law is crucial in fields like electrostatics, as it lays the groundwork for analyzing how charged entities interact within electric fields.

Other options, while related to physics, do not capture the specific essence of Coulomb's Law. The interaction between electric and magnetic fields pertains to electromagnetic theory, while energy loss in circuits relates more to power dissipation principles. The speed of light in a vacuum is a component of relativistic physics defined by a different set of principles entirely.
