Q. In the options given below, let $E\ $denote the rest mass energy of a nucleus and $n$ a neutron. the correct option is
A) $E(_{92}^{236}U)\ > \ E(_{53}^{137}I)\ + \ E(_{39}^{97}Y)\ + \ 2E(n)$
B) $E(_{92}^{236}U)\ < E(_{53}^{137}I)\ + \ E(_{39}^{97}Y)\ + \ 2E(n)$
C) $E(_{92}^{236}U)\ > E(_{56}^{140}{Ba})\ + \ E(_{36}^{94}{Kr})\ + \ 2E(n)$
D) $E(_{92}^{236}U)\ < E(_{56}^{140}{Ba})\ + \ E(_{36}^{94}{Kr})\ + \ 2E(n)$
Explanation
(a) Rest mass of parent nucleus should be greater than the rest mass of daughter nuclei.
