A gold nucleus has a radius of 7.3 10 -15 m and a charge of +79e.
Question:
A gold nucleus has a radius of 7.3 × 10-15 m and a charge of +79e. Through what voltage must an alpha particle, with charge +2e, be accelerated so that it has just enough energy to reach a distance of 2.0 × 10-14 m from the surface of a gold nucleus? (Assume that the gold nucleus remains stationary and can be treated as a point charge.)
