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, 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} {\C}, the mass of the electron =9.11 \times 10^{-31} {\kg}, the mass of the proton =1.67 \times 10^{-27} {\kg} ) : [NEET Re-2022]
