A horizontal, 30-cm-long conducting rod is rolling along two insulating rails that are parallel to the x-axis. The rod is parallel to the y-axis, but moves in the +x direction with a speed of 25 cm/s. The entire assembly is immersed in a uniform magnetic field of 7.26 T in the +z direction (up). The electrons in the rod have moved until they are in equilibrium. One end of the rod is negatively charged, while the other is positively charged. How strong is the electric field (in V/m) inside the moving conductor?
