A circular coil of 50 turns an diameter 24 cm is rotated continuously in a uniform magnetic field of induction `3.6xx10^(-4)`T so as to cut the lines of induction of the field. If the speed of rotation is `5pi`rad/s. the instantaneous induced emf when the plane of the coil is inclined at `30^(@)` to the direction of the field is nearly

Correct Answer - D
`e=e_(0)sinomegat`
`=nAB omega sintheta`
`=50xx3.14xx144xx10^(-4)xx5xx3.14xxsin60`
`=11.08xx10^(-3)V`
`~~11mV`
