The figure shows a solid metal rectangular object moving in the positive direction of an x-axis, through a uniform magnetic field in the positive direction of the y-axis. What potential difference (V) is set up across the object due to the motion? B = 5.00×10−2 T, v = 5.00×103 m/s in positive x direction d1 = 4.00×10−3 m, d2 = 3.00×10−3 m, d3 = 2.00×10−3 m. 0.080 0.120 0.160 0.400 0.240 0.750 0.060 1.00 0.500 0.310
