The figure shows a zero-resistance rod sliding to the right on two zero-resistance rails separated by the distance l = 0.40 m. the rails are connected by a 10.5-ω resistor, and the entire system is in a uniform magnetic field with a magnitude of 0.750 t.

find the speed at which the bar must be moved to produce a current of 0.125 a in the resistor
