    The transmitting antenna of a radio-station is mounted vertically. At a point 10 km due north of the transmitter the peak electric field is\[{{10}^{-3}}\,V\text{/}m.\] The amplitude of the radiated magnetic field is

    A) \[3.33\times {{10}^{-10}}T\]    

    B) \[3.33\times {{10}^{-12}}T\]

    C) \[{{10}^{-13}}T\]       

    D) \[3\times {{10}^{5}}T\]

    Correct Answer: B

    Solution :

    [b] \[{{B}_{0}}=\frac{{{E}_{0}}}{c}=\frac{{{10}^{-3}}}{3\times {{10}^{8}}}=3.3\times {{10}^{-12}}T\]
