QUESTION:
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 \(10^{-10} \mathrm{~m}\). The charges and masses are given on the inside back cover.
ANSWER:Solution 5P Step 1: Here we need to calculate the force of gravity electrical force between electron and proton Considering the data required 31 Mass of electron m = e.1 × 10 kg Mass of proton m = 1p6 × 10 27 kg 11 3 2 1 Gravitational force constant G = 6.67 × 10 m s kg 10 Distance between the particles r = 1 × 10 m Charge of electron q = 1.6 × 10 19 9 Coulomb constant K = 8.9 × 10 F/m
