the principle that the force of attraction or repulsion between two point electric charges is directly proportional to the product of the charges and inversely proportional to the square of the distance between them. A similar law holds for particles with mass
Coulomb's law in American English
(kuˈlɑmz; ˈkuˌlɑmz)
Physics
the statement that the electrostatic force between two charged bodies acts along the line between them, is directly proportionalto the product of their magnitudes, and is inversely proportional to the square of the distance between them: similarlycharged bodies repel one another, while oppositely charged bodies attract one another
