Problem 3
In the figure below, a conducting rod rests on frictionless conducting parallel rails. There is a uniform magnetic going into the page of .50T. The rod is pulled at a constant velocity of 3m/s. The resistance of the rails and rod is negligible; however there is a 0.5F capacitor at then end of the rails. The distance between the rails is 20cm.
a) Calculate the magnitude and direction of the emf in the circuit. Indicate the direction of the emf by drawing and labeling an arrow on the diagram.
b) Calculate charge on the capacitor after the rod has been moving for a long time.
c) Calculate the force on the rod caused by the current passing through it after the rod has been moving for a long time.
