  • question_answer
    1 g of hydrogen is converted into 0.993 g of helium in a thermonuclear reaction. The energy released is [EAMCET (Med.) 1995; CPMT 1999]

    A)            \[63\times {{10}^{7}}J\]  

    B)            \[63\times {{10}^{10}}J\]

    C)            \[63\times {{10}^{14}}J\]

    D)            \[63\times {{10}^{20}}J\]

    Correct Answer: B

    Solution :

                       \[\Delta m=1-0.993=0.007\ gm\]                    \[\therefore E=(\Delta m){{c}^{2}}=(0.007\times {{10}^{-3}}){{(3\times {{10}^{8}})}^{2}}\]\[=63\times {{10}^{10}}J\].
