Review Conceptual Example 3 and the drawing as an aid in solving this problem. A
conducting rod slides down between two frictionless vertical copper tracks at a
constant speed of 3.9 m/s perpendicular to a 0.49-T magnetic field. The resistance of th
rod and tracks is negligible. The rod maintains electrical contact with the tracks at all
times and has a length of 1.4 m. A 1.1-Q resistor is attached between the tops of the
tracks. (a) What is the mass of the rod? (b) Find the change in the gravitational potentia
energy that occurs in a time of 0.26 s. (c) Find the electrical energy dissipated in the
resistor in 0.26 s.
