What is the mass of the rod

Reference no: EM13251908

A conducting rod slides down between two frictionless vertical copper tracks at a constant speed of 4.0 m/s perpendicular to a 0.50-T magnetic field. The resistance of the rod and tracks is negligible. The rod maintains electrical contact with the tracks at all times and has a length of 1.3 m. A resistor is attached 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 s.
