Problem

An electron in the first shell of a hydrogen atom is

5.29\times10^{-11}\,\text{m}

from the nucleus, while an electron in the second shell is

2.12\times10^{-10}\,\text{m}

away. Determine the ratio

F_{\!1}/F_{\!2}

of the attractive force on the first-shell electron to that on the second-shell electron.
