    A current I flowing through the loop as shown in figure. The magnetic field at centre O is-

    A) \[\frac{7{{\mu }_{0}}I}{16R}\otimes \]              

    B) \[\frac{7{{\mu }_{0}}I}{16R}\odot \]

    C) \[\frac{5{{\mu }_{0}}I}{16R}\otimes \]              

    D) \[\frac{5{{\mu }_{0}}I}{16R}\odot \]

    Correct Answer: A

    Solution :

    \[\frac{3}{8}\,\,\frac{{{\mu }_{0}}I}{R}\,\,+\,\,\frac{{{\mu }_{0}}I}{8(2R)}=\frac{7{{\mu }_{0}}I}{16R}\otimes \]
