The nuclei of both 3H and 3He have radii of 1.5 ×10−15 m. With what minimum speed must the electron be ejected if it is to escape from the nucleus and not fall back?

Transcribed Image Text:2. Beta decay is a nuclear process in which a neutron changes into a proton, an electron, and a
neutral particle called a neutrino,
n→p+e+ū,
where is the symbol for an antineutrino. When this change happens to a neutron within the
nucleus of an atom, the proton remains behind in the nucleus while the electron and neutrino
are ejected from the nucleus. The ejected electron is often referred to as a beta particle. One
nucleus that exhibits beta decay is the isotope of hydrogen ³H, called tritium, whose nucleus
consists of one proton and two neutrons. Tritium is radioactive, and it decays to helium,
³H³He+ e +ū.
