The figure below shows a bar of mass m = 0.220 kg that can slide without friction on a pair of rails separated by a distance script l = 1.20 m and located on an inclined plane that makes an angle θ = 34.0° with respect to the ground. The resistance of the resistor is R = 1.20 Ω and a uniform magnetic field 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?

Figure 8-31 shows a ball with mass m ? 0.341 kg attached to the end of a thin rod with length L ? 0.452 m and negligible mass. The other end of the rod is pivoted so that the ball can move in a vertical circle. The rod is held horizontally as shown and then given enough of a downward push to cause the ball to swing down and around and just reach the vertically up position, with zero speed...
