3. A stationary atomic nucleus undergoes radioactive decay and a beta particle (a fast- moving electron) and a neutrino (a subatomic particle) are detected leaving the nucleus at high velocities as shown in the following figure. The momentum of the beta particle is 9.2 10-21 kg-m/s [S] and the momentum of the neutrino is 4.9 10-21 kg m/s [W]. The mass of the remaining nucleus is 3.6 10-25 kg. V= p=4.9 x 10-21 (kg)m/s [W] p=9.2 x 10-21 (kg)m/s [S] a. What is the recoil velocity of the remaining nucleus? b. If the recoil velocity measured is significantly different from the value calculated in part a, what conclusion might a nuclear physicist reach about the decay? 3.
