In a region of a uniform magnetic induction `B=10^(-3)T`, a circular coil of raidus `40cm` and resistance `pi^(3)Omega` is rotated about an axis which is perpendicular to the direction of `vecB` and which forms a diameter of the coil. If the coil rotates at `400` r.p.m., the amplitude of the alternating current induced in the coil is
