it's all due to anamolous behaviour of water here as water at the above surface turns into Ice at 0°C but the water below it is not converted into Ice

mass of proton = 1.67x10⁻²⁷ kg
let 'v₀' be the velocity of proton.
momentum of electron = 1.4x10⁻²⁶ kg m/s
momentum of antineutrino = 6.4 x 10⁻²⁷ kg m/s
(a)electron and antineutrino are ejected in same direction and as the total momentum is conserved the proton should be ejected in opposite direction.
1.67 x 10⁻²⁷ x v₀ = 1.4 x 10⁻²⁸ + 6.4 x 10⁻²⁷
