If $M_o$ is the mass of isotope ${ }_5^{12} B, M_P$ and $M_n$ are the masses of proton and neutron, then nuclear binding energy of isotope is :
  1. $\left(M_o-5 M_p\right) C^2$
  2. $\left(5 M_p+7 M_n-M_o\right) C^2$
  3. $\left(M_0-12 M_n\right) C^2$
  4. $\left(M_o-5 M_p-7 M_n\right) C^2$

Solution

$\begin{aligned} & \text { B.E. }=\Delta m C^2 \\ & \left(5 M_p+7 M_n-M_o\right) C^2\end{aligned}$
