Definition: Coulomb's Law is a law stating the force between two charges is proportional to the amount of charge on both charges and inversely proportional to the square of the distance between them.

F ∝ Q1Q2/r2

where
F = force between the charges
Q1 and Q2 = amount of charge
r = distance between the two charges.
