12. A conducting bar with mass M = 10 kg can slide with no friction along two X X X X X conducting rails separated by distance L = 0.5 m, as shown in the figure. A uniform X X X X 2 Tesla magnetic field points into the page, as indicated by crosses. An external X X X X X X force Fapp pulls the bar to the right with a constant speed v = 3 m/s. What is the R L X X X X X app X magnitude and direction of the induced current in the R = 0.5 Ohm resistor? X X X X X X (1) 6 Amps counter-clockwise X (2) 6 Amps clockwise (3 12 Amps clockwise (4) 12 Amps counter-clockwise (5 3 Amps counter-clockwise
