# Coulomb's Law

Coulomb's Law, a fundamental principle in physics, governs the electrostatic interaction between charged particles. Named after the French physicist Charles-Augustin de Coulomb, this law quantifies the force between two point charges, highlighting the direct proportionality to the product of their charges and the inverse square of the distance between them. As a cornerstone of electromagnetism, Coulomb's Law plays a pivotal role in understanding the behavior of electric fields, aiding in the analysis of diverse phenomena ranging from the behavior of atoms to the design of electronic devices.
