    The mass equivalent of 931 MeV energy is [MP PET 1994; MH CET 2003]

    A)            \[1.66\times {{10}^{-27}}kg\]                                           

    B)            \[6.02\times {{10}^{-24}}kg\]

    C)            \[1.66\times {{10}^{-20}}kg\]                                           

    D)            \[6.02\times {{10}^{-27}}kg\]

    Correct Answer: A

    Solution :

               \[m=\frac{E}{{{c}^{2}}}=\frac{931\times 1.6\times {{10}^{-13}}}{{{(3\times {{10}^{8}})}^{2}}}=1.66\times {{10}^{-27}}kg.\]
