A pair of parallel conducting rails that are separated by a distance =18.9 cm=18.9 cm lies at a right angle to a uniform magnetic field of =0.900 T=0.900 T directed into the screen. A resistor =17.0 Ω=17.0 Ω is connected across the rails. A conducting bar is moved to the left at =2.60 m/s=2.60 m/s across the rails. What is the current in the resistor
