Obtain the binding energy of the nuclei $_{26} Fe^{56}$ and $_{23} Bi ^{209}$ in units of Mev from the following data $m_H= 1.007825\;amu\;m_n= 1.008665\;amu \; m( _{26} Fe ^{56})=55.934939 \;amu\; m( _{83} Fe ^{209})=208.980388 \;amu\;lamu=931.5\;Mev$ Which nucleus has greater binding energy per nucleon ?

Question

$\begin{array}{1 1} B.E/ nucleon \; of\;_{26}Fe^{56} > Bi^{209} \\B.E/ nucleon \; of\;_{83}Bi^{209} > _{26}Fe^{56} \\ B.E / nucleon \;of\;_{26} Fe^{56}= _{83} Bi^{209} \\\text{None of the above} \end{array}$
