    The energy equivalent of 0.5 g of a substance is:                                         [NEET 2020]

    A)  \[4.5\times {{10}^{13}}J\]

    B)                   \[1.5\times {{10}^{13}}J\]

    C)  \[0.5\times {{10}^{13}}J\]      

    D)       \[4.5\times {{10}^{16}}J\]

    Correct Answer: A

    Solution :

    [a] From mass-energy equivalence.
    \[E=m{{c}^{2}}\]
    \[=0.5\times {{10}^{3}}\times {{(3\times {{10}^{8}})}^{2}}\]
    \[=4.5\times {{10}^{13}}J\]
