5. The figure below shows a zero-resistance rod sliding to the right on two zero-resistance rail

Name: 5. The figure below shows a zero-resistance rod sliding to the right on two zero-resistance rails separated by the distance L=0.450 m. The rails are connected by a 12 ohm resistor, and the entire system is in a uniform magnetic field with a magnitude of 0.750 T. a) Find the speed at which the bar must be moved to produce a current of 0.155 A in the resistor. b) If the bar moves to the right, what direction will the current flow?
