Review Conceptual Example 3 and Figure 22.7 . A conducting rod slides down between two frictionless vertical copper tracks at a constant speed of 4.0 perpendicular to a magnetic field. The resistance of the rod and tracks is negligible. The rod maintains electrical contact with the between the tops of the tracks. (a) What is the mass of the rod? (b) Find the change in the gravitational potential energy that occurs in a time of 0.20 . (c) Find the electrical energy dissipated in the resistor in 0.20
