The ratio of Coulomb's electrostatic force to the gravitational force between an electron and a proton separated by some distance is $\displaystyle 2.4 \times 10^{39}$. The ratio of the proportionality constant, $\displaystyle K=\frac{1}{4 \pi \varepsilon_0}$ to the Gravitational constant G is nearly (Given that the charge of the proton and electron each $\displaystyle =1.6 \times 10^{-19} \mathrm{C}$, the mass of the electron = $\displaystyle 9.11 \times 10^{-31} \mathrm{~kg}$, the mass of the proton $\displaystyle =1.67 \times 10^{-27} \mathrm{~kg}$ ) :

(2)
$\displaystyle 10^{20}$
