In a region of uniform magnetic induction `B = 10^(-2)` tesla, a circular coil of radius 30 cm and resistance ` π^2` ohm is rotated about an axis which is perpendicular to the direction of B and which forms a diameter of the coil. If the coil rotates at 200 rpm the amplitude of the alternating current induced in the coil
