A 0.398 m long metal bar is pulled to the left by an applied forceF . The bar rides on parallel metal rails connected through a 45.5A Ω resistor, as shown in the following figure, so the apparatus makes a complete circuit. You can ignore the resistance of the bar and rails. The circuit is in a uniform 0.623 Tmagnetic field that is directed out of the plane of the figure.

1. At the instant when the bar is moving to the left at 5.90 m/s , is the induced current in the circuit clockwise or counterclockwise?

2. At the instant when the bar is moving to the left at 5.90 m/s , what is the rate at which the applied force is doing work on the bar?
