15. The figure above shows a 40.0cm thin metal bar, with mass of 900g, that rests on two conducting metal supports that is connected to a battery and a 25 ohm resistor. The metal bar is placed under a uniform 0.50-T magnetic field. (a) What is the highest voltage, Vmax the battery can have without breaking the circuit at the supports?
