JEE Main 2023 Physics question

A square shaped coil of area 70 having 600 turns rotates in magnetic field of 0.4 Wb, 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 )
