    A) \[9\times {{10}^{6}}J\]                        

    B) \[3\times {{10}^{2}}J\]

    C) \[6\times {{10}^{4}}J\]            

    D)   \[{{10}^{8}}J\]

    Correct Answer: A

    Solution :

    We know that \[PV=\frac{2}{3}E\] \[E=\frac{3PV}{2}=3\times \frac{3\times {{10}^{6}}}{2}\times 2=9\times {{10}^{6}}J\]
