A neutron initially at rest,decays into a proton,an electron and an antineutrino. The ejected electron has a momentum of 1.4×10−26 kg−ms and the antinuetrino 6.4×10−27 kg−ms.Find the recoil speed of the proton (a) if the electron and the antineutrino are ejected along the same direction and (b) if they are ejected along perpendicular directions.Mass of the proton =1.67×10−27 kg. |
