Suppose we think of fission of a $_{26}Fe^{56}$ nucleus into two fragment $_{13} Al ^{26}$. Is the fission energetically possible ? Argue by working out Q of the process. cives.

Question

$\begin{array}{1 1} Q= 26.88\;Mev ; possible \\ Q=-26.88 \;Mev \;energetically\;not\;possible \\ Q=-26.88 \;Mev \;cannot\;be\;determined \\ none\;of\;these \end{array}$
