Problem- Atomic physicists ignore the effect of gravity within an atom. To see why, calculate and compare the gravitational and electrical forces between an electron and a proton separated by 1.4 x 10-10 m. The mass of the proton is 1.6726 x 10 -27 kg and that of the electron is 9.1094 x 10-31 kg. The charge of the proton and electron is the same, e = 1.602 x 10-19 Coulombs. The gravitational constant is 6.67x 10-11 Nm2kg-2.

a) The force due to the gravitational interaction between the two particles is?

b) The force due to the electrostatic interaction between the two particles is?
