Assignment Booklet 10 Physics Assignment Booklet 11 11. An isotope emits an electron and an anti-neutrino during radioactive decay. The electron moves east with a momentum of 9.28 x 10-26 kgm/s, and the anti-neutrino moves north with a momentum of 7.47 x 10-27 kgm/s as shown in the diagram below. N anti-neutrino electron recoiling nucleus a. Determine the momentum of the recoiling nucleus. Determine the angle to the nearest 1/100th degree
