  • question_answer
    If a star can convert all the He nuclei completely into oxygen nuclei, the energy released per oxygen nuclei is [Mass of \[He\] nucleus is 4.0026 amu and mass of Oxygen nucleus is 15.9994  mu]

    A)  7.6 MeV

    B)                     56.12 MeV

    C)  10.24 MeV  

    D)         23.9 MeV

    Correct Answer: C

    Solution :

    [c] \[4_{2}^{4}He\xrightarrow{{}}_{8}^{16}O\] \[B.E.=\Delta m\times 931.5\text{ }MeV\] \[=(4\times 4.0026-15.9994)\times 931.5=10.24MeV\]
