    The number of neutrons released when \[_{92}{{U}^{235}}\] undergoes fission by absorbing \[_{0}{{n}^{1}}\] and \[{{(}_{56}}B{{a}^{144}}{{+}_{36}}K{{r}^{89}})\] are formed, is                                    [Pb. PMT 2000]

    A)            0    

    B)            1

    C)            2    

    D)            3

    Correct Answer: D

    Solution :

                       \[_{92}{{U}^{235}}{{+}_{0}}{{n}^{1}}{{\to }_{92}}{{U}^{236}}\]and                    \[_{92}{{U}^{236}}{{\to }_{56}}B{{a}^{144}}{{+}_{36}}K{{r}^{89}}+{{3}_{0}}{{n}^{1}}+Q\].
