Moving Charges And Magnetism

A metal conductor of length \(1 \mathrm{~m}\) rotates vertically about one of its ends at an angular velocity of \(5 \mathrm{~rad} / \mathrm{s}\). If horizontal component of earth's magnetic field is \(0.2 \times 10^{-4} \mathrm{~T}\), then the e.m.f. developed between the two ends of the conductor is
