A gold nucleus has a radius of 7.3×10-15 m and a charge of +79e. Through what voltage must an α-particle, with its charge of +2e, be accelerated so that it has just enough energy to reach a distance of 2.5×10−14 m from the surface of a gold nucleus? (Assume the gold nucleus remains stationary and can be treated as a point charge.)
