Question
Consider a hydrogen atom in its 1s state (ground state) and assume (for simplicity) that
the electron and the proton are separated by a constant distance a, = 5.292 × 10–1'm
(called the Bohr radius).
(a) Calculate the gravitational force between these two charges. (use: Fg = G"m2)
(b) Calculate the electric force between these two charges. (use: Fe = k«l&i[IQzl)
(c) Calculate the ratio of these two forces to appreciate the strength of the electric force
in comparison to the gravitational force.
