    In a nuclear reactor, the fuel is consumed at the rate of 1 mg/s. The power generated in kilowatt is [DCE 2003]

    A)            \[9\times {{10}^{4}}\]      

    B)            \[9\times {{10}^{7}}\]

    C)            \[9\times {{10}^{8}}\]      

    D)            \[9\times {{10}^{12}}\]

    Correct Answer: B

    Solution :

                       Power \[P=\frac{Energy}{time}=\frac{m{{c}^{2}}}{t},\]= 1 ´ 10?6´ (3 ´ 108)2 = 9 ´ 1010 W = 9 ´ 107 kW.
