Answer 1

Answer: electric force between electron and proton is greater than gravitational force

Explanation:

by coulomb's law

Fe = K Qe xQp

              d^2

Fe = 9 x 10^9 $Nm^{2} / C^{2}$ x 1.6 x 10^9 x 1.6 x 10^9 / [5.3 x 10^-11] ^2$m^{2}$

    = 9 × 1.6 × 1.6 / 28.09  x 10  x 10^-7

    = 8.2 x 10^-8 N  

By Newton's Law of Universal Gravitation

Fg = G m$^1$ x m$^{2}$ / d^2

   = 6.67 x 10^-11 $Nm^{2}$ x 9.1 x 10^-31 $kg$ x 1.7 x 10^-27

   = 6.67 x 9.1 x 1.7 x 10^-69$N$ / 28.09

   = 3.67 X 10 ^-69

∴ electric force between electron and proton is greater than gravitational force between electron and proton
