A bar of length d = 1 m is free to slide without fri ction on horizontal rails as shown in Figure. A uniform magneti c field B = 1.4 T is directed into the pl ane of the figure. Left ends of the rails are connected to a circuit composed ofresistances, R1 = 400, R2 = 10 N, and R3 = 15N, a solenoid with inductance L = 0.5 H , a battery with emf ɛ = 180 V , and a switch S. The bar has mass m = 150 g and resistance R = 5 N. Ignore all other resistance in the circuit due to connecting wires and the rails. Just after the switch is closed, what is the accelerati on of the bar?
