Question 192 of 239

If MoM_o is the mass of isotope 512B,MP{ }_5^{12} B, M_P and MnM_n are the masses of proton and neutron, then nuclear binding energy of isotope is :

Show answer and solution

Answer: (B) (5Mp+7Mn−Mo)C2\left(5 M_p+7 M_n-M_o\right) C^2

 B.E. =ΔmC2(5Mp+7Mn−Mo)C2\begin{aligned} & \text { B.E. }=\Delta m C^2 \\ & \left(5 M_p+7 M_n-M_o\right) C^2\end{aligned}
