Assume That A Neutron Breaks Into A Proton And An Electron. What Will Be The Energy Released During This Process?

As given :

Neutron \( \rightarrow \)Proton + Electron

A we know:

Mass of neutron,\( m_{n} = 1.6725 * 10^{-27} kg \)

Mass of proton,\( m_{p} = 1.6725 * 10^{-27} kg\)

Mass of electron, \( m_{e} = 9 * 10^{-31} kg \) \( \Delta m = (m_{p} + m_{e}) – m_{n} \) \( \Rightarrow [1.6725 * 10^{-27} + 9 * 10^{-31} – 1.6725 * 10^{-27}]kg \) \( \Rightarrow 9 * 10^{-31} kg \)

The energy released during this process, E = \( \Delta mc^{2}\) \( 9 * 10^{-31} * (3 * 10^{8})^{2} J \) \( \Rightarrow \frac{9 * 10^{-31} * 9 * 10^{16}}{1.6 * 10^{-13}} \) \( \Rightarrow 0.51 MeV \)
