A conducting rod with length 10cm, mass 20g and resistance 0.02 Q can frictionlessly slide straight downward on a conducting track (with negligible resistance) as shown. A uniform 1.0T magnetic ?eld is applied in the direction shown. 0 (6pm) If the rod slides down the track with velocity, v, what voltage is induced on the rod and what current, if any, ?ows through the rod and in which direction? (Write an equation with numbers and v as a variable.) . (4 pts) If the rod continues to slide with velocity v, what is the magnetic force on the rod and in which direction? - (4pm) Ifthe rod accelerates due to gravity, is there a speci?c velocity where the magnetic force cancels the force due to gravity on the rod? If so, what is it?
