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 the alpha particle when it is detected (velocity final) in the laboratory? Assume the thorium nucleus remains at rest
There is no unit of every data.We have to calculate the speed of
alpha particle
