A circular loop made of a stretched conducting elastic material has a 1.23 m radius and is placed in a uniform magnetic field of 785 mT. The direction of the area of loop plane is perpendicular to the magnetic field. When stretching of the loop is released, the radius of the loop starts to decrease at an instantaneous rate of 7.50 cm/s. Calculate the emf induced in the loop at that instant
