    The net magnetic moment of two identical magnets each of magnetic moment \[{{M}_{0}},\] inclined at \[60{}^\circ \] with each other is

    A) \[{{M}_{0}}\]              

    B)        \[\sqrt{2}\,{{M}_{0}}\]

    C) \[\sqrt{3}\,{{M}_{0}}\]

    D)         \[2\,{{M}_{0}}\]

    Correct Answer: C

    Solution :

    [c] \[{{M}_{net}}=\sqrt{M_{0}^{2}+M_{0}^{2}+2M_{0}^{2}\cos 60{}^\circ }\] \[=\sqrt{3M_{0}^{2}}=\sqrt{3}{{M}_{0}}\]
