    A conducting sphere of radius R = 20 cm is given a charge \[Q\]= 16\[\mu \]C. What is \[\hat{E}\] 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£ at the centre of sphere is zero. Since, the centre of sphere is placed with in the Gaussian surface. Hence,\[E=0\].
