A radioactive nucleus at rest decays into a second nucleus, an electron, and a neutrino. The electron and neutrino are emitted at right angles and have momenta of Pe = 9.20×10-23 kg. m/s and Pv = 5.74x10-23 kg. m/s, respectively. (Figure 1)
Determine the angle between the momentum of the electron and the momentum of the second (recoiling) nucleus. Express your answer using three significant figures.
