Using data from Table 3.3, calculate the ratio between the electrostatic force and the gravitational force between the proton and the electron in a hydrogen atom, if the distance between the electron and the proton is r = 5.3 × 109 m. The universal gravitational constant G = 6.67 × 10-11 m3 kg-1 s-2, and Coulomb's constant k = 9.0 × 109 N m2/C2.
