If M_o is the mass of isotope _5^ 12 B, M_P and M_n are the masses...

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 :

Options

A $\left(M_o-5 M_p\right) C^2$
B $\left(5 M_p+7 M_n-M_o\right) C^2$
C $\left(M_0-12 M_n\right) C^2$
D $\left(M_o-5 M_p-7 M_n\right) C^2$

Correct answer

B. $\left(5 M_p+7 M_n-M_o\right) C^2$

Step-by-step solution

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