(a) What is the ratio of electric force to the gravitational force between them?

(b) If you move the electron and proton either closer or further apart, is there a distance at which the gravitational force is bigger than the electric force?

Electrostatic Constant (K) = 8.99 x 10⁹ N.m²/C²
Gravitational Constant (G) = 6.67 x 10^-11 N.m²/kg²
Mass of electron = 9.11 x 10^-31 kg
Mass of proton = 1.67 x 10^-27 kg
Charge of electron = -1.6 x10^-19 C
Charge of proton = +1.6 x10^-19 C
