6) A conductor, 500 mm long, is moved at a uniform speed at right angles to its length and to a uniform magnetic field having a density of 0.4 T. If the e.m.f. generated in the conductor is 2 V and the conductor forms part of a closed circuit having a resistance of 0.5 Ω, calculate: a) the velocity of the conductor in metres per second; b) the force acting on the conductor in newtons; c) the work done in joules when the conductor has moved 600 mm.
