A conducting bar of length l moves to the right on two frictionlessrails, as shown in the figure below. A uniform magnetic fielddirected into the page has a magnitude of 2.90 T. Assume script l =39 cm and R = 9.1 O.

(a) At what constant speed should the bar move to produce an 8.3 mAcurrent in the resistor?
m/s
What is the direction of this induced current?
(b) At what rate is energy delivered to the resistor?
mJ/s
(c) Explain the origin of the energy being delivered to theresistor.
