In the figure, a metal wire of mass m = 20.7 mg can slide with negligible friction on two horizontal parallel rails separated by distance d = 3.78 cm. The track lies in a vertical uniform magnetic field of magnitude 56.4 mT. At time t = 0 s, device G is connected to the rails, producing a constant current i = 9.21 mA in the wire and rails (even as the wire moves). At t = 78.4 ms, what are the wire's (a) speed and (b) direction of motion? (a) Number (b) to the left + i 0.74366 ook and Media Units B m/s m B
