An athlete peddles a stationary tricycle whose pedals are attached to a coil having 100 turns each of area 0.1 m2. The coil, lying in the X-Y plane, is rotated, in this plane, at the rate of 50 rpm, about the Z-axis, in a region where a uniform magnetic field, 
tesla, is present. Find the
(i) maximum emf
(ii) average emf generated in the coil over one complete revolution
