A square shaped coil of area `70 cm^2` having `600` turns rotates in a magnetic field of `0.4 wbm^(–2)` , about an axis which is parallel to one of the side of the coil and perpendicular to the direction of field. If the coil completes `500` revolution in a minute, the instantaneous emf when the plane of the coil is inclined at `60@` with the field, will be ––––––V. (Take `pi = (22)/7 )`
