    If M0 is the mass of an oxygen isotope\[_{8}{{O}^{17}},\]\[{{M}_{P}}\]and \[{{M}_{n}}\] are the masses of a proton and a neutron, respectively, the nuclear binding energy of the isotope is

    A)  \[({{M}_{0}}-8{{M}_{P}}){{c}^{2}}\]

    B)         \[({{M}_{0}}-9{{M}_{n}}){{c}^{2}}\]

    C)         \[{{M}_{0}}{{c}^{2}}\]                  

    D)         \[({{M}_{0}}-17{{M}_{n}}){{c}^{2}}\]

    Correct Answer: B

    Solution :

    Blinding energy \[BE=({{M}_{nucleus}}-{{M}_{nucleons}})\,{{c}^{2}}\]        \[=({{M}_{O}}-8{{M}_{p}}-9{{M}_{n}})\,{{c}^{2}}\]
