In the figure shown below, a 250.0 g metal bar, 1.5 m long and itself having a resistance of 10.0 Ω, rests horizontally on conducting rails. The bar, which is free to slide along the rails, is in a uniform magnetic field of magnitude 1.75 T. What is the acceleration of the bar when the switch S is closed? a.) 3.6 m/s2 b.) 5.1 m/s2 c.) 7.7 m/s2 d.) 9.5 m/s2 e.) none of these

A bar with a length of L = 0.50 m slide without friction on horizontal rails, as shown in Figure 1. There is a uniform magnetic field of B = 2.0 T directed into the plane. At one end of the rails, there is a battery with an emf of ε = 15 V and a switch. The bar has a mass of 0.90 kg and a resistance of 5.0 Ω, while any other resistance in the circuit is negligible. The switch is closed at t = 0. Figure 1 (a) Plot the speed of the bar as a function of time. (b) What is the acceleration of the bar immediately after the switch is closed? (c) What is the acceleration of the bar when its speed reaches 2.0 m/s? (d) What is the terminal speed of the bar?
