Problem

An electron in a singly ionized helium ion, He

^{+}

, is located

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

from the nucleus, whose charge is

+2e

. A hydrogen atom has its electron

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

from its

+e

nucleus. What is the ratio of the magnitude of the attractive electrostatic force in He

^{+}

to that in H? a)
