        A conducting sphere of radius R = 20 cm is given a charge\[Q=16\mu C\]. What is E at centre?

    A)  \[3.6\times {{10}^{6}}N/C\]       

    B)  \[1.8\times {{10}^{6}}N/C\]

    C)  Zero                     

    D)  \[0.9\times {{10}^{6}}N/C\]

    Correct Answer: C

    Solution :

                    The value of E at the centre of sphere is zero Since, the centre of sphere is placed within the Gaussian surface. Hence,\[E=0\].
