G The figure shows a metallic block, with its faces parallel to coordinate axes. The block is in a uniform magnetic field of magnitude 0.020 T. One edge length of the block is 24 cm; the block is not drawn to scale. The block is moved at 2.9 m/s parallel to each axis, in turn, and the resulting potential difference V that appears across the block is measured. With the motion parallel to the y axis, V-19 mV; with the motion parallel to the z axis, V-12 mV; with the motion parallel to the x axis, V-0. What are the block lengths (a) d, (b) d,, and (c) d,?
