Odisha Board Solutions for Chapter: Nuclear Physics, Exercise 1: MODEL QUESTIONS

A free neutron decays to a proton and electron and antineutrino $\left(\mathrm{n}\to \mathrm{\rho }+{\mathrm{e}}^{-}+{\overline{\mathrm{\nu }}}_{\mathrm{e}}\right)$. Calculate the energy produced in this reaction in $\mathrm{MeV}$.

Given     

$$\begin{gathered} \mathrm{m}\left({}_1\mathrm{e}^0\right)=9\times {10}^{-31} \mathrm{Kg} \\ \mathrm{m}\left({}_0\mathrm{n}^1\right)=1.6747\times {10}^{-27} \mathrm{Kg} \\ \mathrm{m}\left({}_1\mathrm{H}^1\right)=1.6725\times {10}^{-27} \mathrm{Kg} \end{gathered}$$
