3. A thin, 46.0 cmcm long metal bar with mass 750 g rests on, but is not attached to, two metallic supports in a uniform magnetic field with a magnitude of 0.440 T, as shown in. A battery and a resistor of resistance 24.0 N are connected in series to the supports. a) What is the largest voltage the battery can have without breaking the circuit at the supports?
