Question: chapter 28 problem 046 in the figure a metal wire...

Question details

Chapter 28, Problem 046 In the figure, a metal wire of mass m26.2 mg can slide with negligible friction on two horizontal parallel rails separated by distance d = 2.13 cm. The track lies in a vertical uniform magnetic field of magnitude 58.2 mT. At time t-0 s, device G is connected to the rails, producing a constant current, = 7.69 mA in the wire and rails (even as the wire m oves). At t = 73.1 ms, what are the wires (a) speed and (b) direction of motion? n (a) Number | Units the tolerance is +/-590
