A hydrogen nucleus has a radius of 1 x 10-15 m and the electron is about 5.3 x 10-11 m from the nucleus. Assume the hydrogen atom is a ball with a radius of about 5.3 x 10-11 m and the nucleus is a ball with a radius of 1 x 10-15 m. How much work (in electron volts) must be performed by an external force to bring in another proton (from very far away) to the "surface" of the nucleus?
