Physics - Electrostatics Question with Solution | TestHub

The ratio of coulomb's electrostatic force to the gravitational force between an electron and a proton separated by some distance is $2.4\times 10^{39}$. The ratio of the proportionality constant, $\mathrm{K}=$ $\frac{1}{4\pi {\epsilon }_0}$ to the Gravitational constant G is nearly (Given that the charge of the proton and electron each $=1.6\times 10^{-19}\mathrm{C}$, the mass of the electron $=9.11\times 10^{-31}\mathrm{kg}$, the mass of the proton $=$ $1.67\times 10^{-27}\mathrm{kg})$NEET 2022 (Phase 2)
