Q. In a process a neutron which is initially at rest, decays into a proton, an electron and an antineutrino. The ejected electron has a momentum of

p_{1} = 2.4 \times 10^{- 26} k g m / s

and the antineutrino has

p_{2} = 7.0 \times 10^{- 27} k g m / s

. Find the recoil speed of the proton if the electron and the antineutrino are ejected (a) along the same direction (b) in mutually perpendicular directions (Mass of the proton

Q. 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-m/s and the antineutrino 6.4 × 10⁻²⁷ kg-m/s. 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.
