(8e28p44) A metal wire of mass m = 0.250 kg slides without friction on two horizontal rails spaced a distance d = 0.18 m apart, as in the figure. The track lies in a vertical uniform magnetic field B = 0.60 T. There is a constant current i = 0.30 A through generator G, along one rail, across the wire, and back down the other rail. Find the speed and direction of the wire's motion as a function of time,...
