Chapter , Problem 46(choose chapter or problem)
In Fig. 28-44, a metal wire of mass m 24.1 mg can slide with negligible friction on two horizontal parallel rails separated by distance d ! 2.56 cm. The track lies in a vertical uniform magnetic field of magnitude 56.3 mT. At time t ! 0, device G is connected to the rails, producing a constant current i ! 9.13 mA in the wire and rails (even as the wire moves). At t ! 61.1 ms, what are the wires (a) speed and (b) direction of motion (left or right)?

ANSWER:Problem 46
In the figure, a metal wire of mass m=24.1 mg can slide with negligible friction on two horizontal parallel rails separated by distance d=2.56 cm. The track lies in a vertical uniform magnetic field of magnitude 56.3 mT. At time t=0, device G is connected to the rails producing a constant current i=9.13 mA in the wire and rails (even as the wire moves). At t=61.1 ms, what are the wires
(a) Speed and
(b) Direction of motion (left or right)?
