Coulomb's constant

Coulomb's constant is a fundamental value used in physics to describe the strength of the electric force between two charged objects. It helps quantify how much force there is based on the amount of charge on each object and how far apart they are. Specifically, it appears in Coulomb's law, which calculates the force: larger charges or closer distances result in a stronger force. The constant ensures the units are consistent, allowing scientists to predict and understand electrostatic interactions accurately across different situations. Its value is approximately 8.9875 × 10⁹ N·m²/C².
