A simple model of a hydrogen atom pictures the electron and proton as point charges separated by 0.050 nm, and in Example 18.1 we calculated the associated electric potential energy. If the electron is initially at rest, how much work is required to “break apart” these two charges, that is, to separate them by a very large distance?

(reference example 18.1)
