QUESTION 3 An 80-cm-long conducting rod moves to the right with a constant velocity along frictionless metal rails "ab" and “de" as shown in the diagram below. At the same time, a uniform magnetic field of strength 1.8 T points out of the page and perpendicular to the plane of the rod-and-frame device (the positive z- direction). The resistance in the closed loop is 7.00 N. If the current across the resistor is 2.0 A, what is the speed of the conducting rod along the rails?
