A 4.57 MeV alpha particle from radium226Ra decay makes a head-on collision with a uranium nucleus. A uranium nucleus has 92 protons.
a) What is the force on the alpha particle at the instant when it is at the distance of closest approach?
b) What is the distance of closest approach of the alpha particle to the center of the nucleus? Suppose that the uranium nucleus remains at rest and that the distance of closest approach is much larger than the radius of the uranium nucleus.
