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 9.0 fm apart and essentially at rest.

Find their speeds when they're a great distance apart. Treat each particle as a spherical charge distribution.

Express your answers using two significant figures.

In the form of radioactive decay known as alpha decay, an unstable nucleus emits a helium-atom nucleus, which is called an alpha particle. An alpha particle contains two protons and two neutrons, thus having mass m=4u and charge q=2e. Suppose a uranium nucleus with 92 protons decays into thorium, with 90 protons, and an alpha particle. The alpha particle is initially moving at velocity= 5.89 *10^8, and the radius of alpha particle is r=3.1* 10^ -11.What is the speed of...
