The gure below shows a bar of mass m = 0.215 kg that can slide without friction on a pair of rails separated by a distance i = 1.20 m and located on an inclined plane that makes an angle 9 = 35.00 with respect to the ground. The resistance of the resistor is R = 2.70 0, and a uniform magnetic eld of magnitude B = 0.500 T is directed downward, perpendicular to the ground, over the entire region through which the bar moves. With what constant speed v does the bar slide along the rails? m/s Need Help
