Ans. Statement: The force between two point charges varied inversely as the square of the distance between the charges and directly proportional to the product of magnitude of the two charges and acted along the line joining the two charges
Explanation: Let $q_{1}\&q_{2}$ are two point charges and separated by a distance $r$ in vacuum $$\begin{array}{c}{\mathrm{F\propto q_{1}q_{2}}}\\{\mathrm{F\propto\frac{1}{r^{2}}}}\\{\mathrm{F\propto\frac{q_{1}q_{2}}{r^{2}}}}\\ {\mathrm{F=\frac{1}{4\pi\varepsilon_{\circ}}\frac{q_{1}q_{2}}{r^{2}}}} \end{array}$$Where $\varepsilon_{\circ}$-Permitivity of free space.
