    A coil of cross-sectional area \[1.25\times {{10}^{3}}m/s\] having 30 turns is making 1800 rev/min in a magnetic field of 1 T. The peak value of the induced emf is

    A)  \[\frac{hv}{4}\]                               

    B)  \[\frac{hv}{3}\]

    C)  \[\frac{hv}{2}\]                               

    D)  \[\frac{2hv}{3}\]

    Correct Answer: C

    Solution :

                    Induced emf \[{{e}_{\max }}=NBA\omega \] \[{{e}_{\max }}=30\times 1\left( \frac{400}{10000} \right)\times \left( 1800\times \frac{2\pi }{60} \right)\] \[{{e}_{\max }}=226V\]
