    A metal rod of length 2 m is rotating with an angular velocity of 100 rad/s in a plane perpendicular to uniform magnetic field of T. The potential difference between the ends of rod is

    A)                  30 V                                     

    B)                  40 V

    C)                  60 V                                     

    D)                  600 V

    Correct Answer: C

    Solution :

                     \[e=\frac{1}{2}B{{t}^{2}}\omega =\frac{1}{2}\times 0.3\times 2\times 2\times 100=60V\]
