    When the mass equal to one a.m.u. is converted completely into energy, then the energy produced is

    A) \[1.5\times {{10}^{-18}}Joule\] 

    B) \[1.5\times {{10}^{-14}}Joule\]

    C) \[1.5\times {{10}^{-12}}Joule\] 

    D) \[1.5\times {{10}^{-10}}Joule\]

    Correct Answer: D

    Solution :

    \[E=\Delta m{{c}^{2}}\]     \[=931.5MeV\]     \[=931.5\times {{10}^{5}}\times 1.6\times {{10}^{-19}}J\]     \[=1.5\times {{10}^{-10}}J\]
