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

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

    B)         \[1.8\times {{10}^{6}}N\text{/}C\]         

    C)  zero                     

    D)         \[0.9\times {{10}^{6}}N\text{/}C\]

    Correct Answer: C

    Solution :

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