Answer:

Coulomb’s law gives the magnitude Fe of the electric force between the electron and proton as

Fe=k|q1q2|r2=ke2r2

where k=8.99×109N?m2/C2. The gravitational force F? g has magnitude Fg:

Fg=Gm1m2r2=Gmempr2

where G=6.67×10?11N?m2/kg2. The ratio of the two forces is

FeFgFeFg===(ke2r2)(r2Gmemp)=ke2Gmemp(8.99×109N?m2/C26.67×10?11N?m2/kg2)×(1.60×10?19C)2(9.11×10?31kg)(1.67×10?27kg)2.27×1039
