This physical rule was developed out of its namesake's attempts to generalize Priestley's law starting around 1785, and its discovery was made possible by the inversion of a sensitive torsion balance.
This physical rule was developed out of its namesake's attempts to generalize Priestley's law starting around 1785, and its discovery was made possible by the inversion of a sensitive torsion balance. The use of cgs units simplifies the expression of this law by normalizing the charge to its constant of proportionality, which is equal to 1/(4πε) ["one over four pi epsilon"], or about  ["eight point nine nine times ten to the ninth meters per farad"]. For ten points, name the electrostatic law that states that the force between two point charges is equal to the product of their charges divided by the square of the distance between them.
