The inverse square law in electrostatics is$\left|\vec{F}\right| = \frac{e^{2}}{\left(4\pi\varepsilon_{0}\right)\cdot r^{2}}$ for the force between an electron and a proton. The $(\frac{1}{r})$ dependence of $|\vec{F}|$ can be understood in quantum theory as being due to the fact that the ??article? $\left|\vec{F}\right| = \frac{e^{2}}{\left(4\pi\varepsilon_{0}\right)r^{2}}\left[\frac{1}{r^{2}} + \frac{\lambda}{r}\right] \cdot exp \left(-\lambda r\right)$ where $\lambda = m_pc/?$ and $?= \frac{h}{2\pi}$ The change in the ground state energy $(eV)$ of a $H$-atom if $m_p$ were $10^{-6}$ times the mass of an electron.
