The distance between the electron and proton in hydrogen atom is \( 5.3 \times 10^{-11} \mathrm{~m} \). Determine the magnitude of the ratio of electrostatic and gravitational force between them.
Given \( m_{e}=9.1 \times 10^{-31} \mathrm{~kg}, m_{p}=1.67 \times 10^{-27} \mathrm{~kg} \), \( e=1.6 \times 10^{-19} \mathrm{C} \) and \( G=6.67 \times 10^{-11} \mathrm{Nm}^{2} \mathrm{~kg}^{-2} \)
