6. Two thin parallel bars 0.1m long spaced 0. Im apart move with equal constant velocities of 10 m/s in perfect contact with resistance less rails as shown in the next figure. The resistance of cach bar is 0.01 ohm. The z-component of the static magnetic field varies as Bz = 10' xy Tesla in the region between the rails. Find the reading of the voltmeter.
