If you mean Coulomb's Law, then it's that the magnitude of the force of attraction or repulsion between two charged particles of charges \(q_1\) and \(q_2\) separated by a distance \(r\) is given by the following formula. \[F = \frac{1}{4\pi \epsilon_0} \frac{q_1 q_2}{r^2}\]Here, \(\epsilon_0\) is a fundamental constant called the permittivity of free space.
