Question

A rectangular coil of single turn,  having area A, rotates in a uniform magnetic field B with an angular velocity  ω      about an axis  perpendicular to the field. If initially the plane of coil is perpendicular  to the field, then the average induced e.m.f. when it has rotated through $$900$$      is
