An elastic conducting material is stretched into a circular loop of 12.6 cm radius. It is placed with its plane perpendicular to a uniform 1.17 T magnetic field. When released, the radius of the loop starts to shrink at an instantaneous rate of 57.9 cm/s. What emf is induced in volts in the loop at that instant? Number i Units
