T h e n t h e c o u l o m b s f o r c e b e t w e e n t h e m, F α \frac{q_{1} q_{2}}{r^{2}} \Rightarrow F = \frac{1}{4 {πε}_{0}} \times \frac{q_{1} q_{2}}{r^{2}} ε_{0} \to Permittivity of free space . Here, Fα \frac{1}{r^{2}} Force is inversely proportional to square of the distance r . That is why it is called as inverse square law . Regards . .$
