WebCoulomb's Law is a mathematical formula that describes the electrostatic interaction between two charges particles that was first proposed by the French physicist Charles Coulomb (1736–1806). Coulomb's law is often called an inverse square law, as the force decreases as a function of the square of the distance between the two particles.
