Coulomb’s law

Physics

The force (sometimes called the Coulomb force) between two charged particles, regarded as point charges Q₁ and Q₂ a distance d apart, is proportional to the product of the charges and inversely proportional to the square of the distance between them. The law is now usually stated in the form F=Q₁Q₂/4πε‎d², where ε‎ is the absolute permittivity of the intervening medium. ε=ε‎_rε‎₀, where ε‎_r is the relative permittivity (the dielectric constant) and ε‎₀ is the electric constant. The electric field surrounding a point charge is called the Coulomb field and the scattering of charged particles by the Coulomb field surrounding an atomic nucleus is called Coulomb scattering. The law was first published by Charles de Coulomb in 1785. This law was found independently by Henry Cavendish.

Chemistry

The law stating that the force between two electrically charged point particles is proportional to the product of the two charges and inversely proportional to the square of the distance between the particles; the force is attractive when the particles have opposite charges and repulsive when the particles have the same charge. It was first stated by Charles Augustin de Coulomb (1736–1806) in 1785 but discovered independently by Henry Cavendish two years earlier.

Electronics and Electrical Engineering

The mutual force, F, between two electrostatic point charges, q₁ and q₂, that results from the interaction of the electrostatic fields surrounding them is given by
$F = \frac{q_{1} q_{2}}{4 π ε r^{2}}$
where r is the distance between the charges and ε the permittivity of the medium. Coulomb’s law thus relates electrical and mechanical phenomena. See also Ampere’s law.
