A uranium nucleus (mass 238 u, charge 92e) decays, emitting an alpha particle (mass 4 u
Chapter 22, Problem 70(choose chapter or problem)
A uranium nucleus (mass 238 u, charge 92e) decays, emitting an alpha particle (mass 4 u, charge 2e) and leaving a thorium nucleus (mass 234 u, charge 90e). At the instant the alpha particle leaves the nucleus, the centers of the two are 7.4 fm apart and essentially at rest. Treating each particle as a spherical charge distribution, find their speeds when theyre a great distance apart.
