    The binding energies per nucleon for a deuteron and an \[\alpha \]-particle are \[{{x}_{1}}\,\] and \[{{x}_{2}}\] respectively. What will be the energy Q released in the reaction \[_{1}{{H}^{2}}{{+}_{1}}{{H}^{2}}{{\to }_{2}}{{H}^{4}}+Q\]

    A)  \[4\left( {{x}_{1}}+{{x}_{2}} \right)\]

    B)                     \[4\left( {{x}_{2}}-{{x}_{1}} \right)\]

    C)  \[2\left( {{x}_{1}}+{{x}_{2}} \right)\]  

    D)         \[2\left( {{x}_{2}}-{{x}_{1}} \right)\]

    Correct Answer: B

    Solution :

    [b] \[Q=4({{x}_{2}}-{{x}_{1}})\]
