    If the energy released in the fission of one nucleus is 200 MeV. Then the number of nuclei required per second in a power plant of 16 kW will be:

    A) \[0.5\times 1014\]

    B)  \[0.5\times {{10}^{12}}\]

    C) \[5\times {{10}^{12}}\]

    D)  \[5\times {{10}^{14}}\]

    Correct Answer: D

    Solution :

     Given : Energy released per second E = 200 MeV \[=200\times {{10}^{6}}\times 1.6\times {{10}^{-19}}\] \[=3.2\times {{10}^{-11}}\]joule Power \[P=16kW=16\times {{10}^{3}}\]watt As the number of nuclei is given by \[n=\frac{P}{E}=\frac{16\times {{10}^{3}}}{3.2\times {{10}^{-11}}}=5\times {{10}^{14}}\]
