A coil of wire of area 0.2 m2 containing 1000 turns is placed in a magnetic field of induction √2 T. At time t = 0, the axis of the coil and the direction of magnetic field are along z-direction. The coil is rotated by an angle 45° in 2s about y-axis. Assuming the constant angular speed, the average e.m.f induced in the coil is approximately
