A radioactive nucleus at rest decays into a second nucleus, and electron, and a neutrino. The electron and neutrino are emitted at right angles and have moment a of 9.30 x 10-23 kg m/s and 5.40 x 10-23 kg m/s, respectively. What are the magnitude and direction of the momentum of the second (recoiling) nucleus?
