5. ssm The drawing shows three SP identical rods (A, B, and C) N a moving in different planes. A VC y constant magnetic field of magnitude 0.45 T is directed B along the +y axis. The length of 1 2 2 each rod is L = 1.3 m, and the y 2 rods each have the same speed, AW VA = UB = Vc = 2.7 m/s. For each rod, find the magnitude of x the motional emf, and indicate which end (1 or 2) of the rod is positive
