Coulumb's Law

Path: 一 etc 一/Engineering/Electrical Engineering/Electricity and Magnetism/Coulumb's Law.mdUpdated: 2/3/2026

Coulomb's law states that the force between two objects is directly proportional to the product of the magnitudes of their charges and inversely proportional to the square of the distance between them. This means that as the distance between the objects increases, the force diminishes rapidly, and as the magnitude of each object's charge increases, the force becomes stronger.
