A pair of parallel conducting rails that are 12 cm apart lies at right angles to a uniform magnetic field of 0.8 T directed into the page. A 15-ohm resistor is connected across the rails. A conducting bar is moved to the right at 2m/s across the rails.
1) What is the current in the resistor? (Express your answer to two significant figures.)
2) What is the magnetic force on the bar due to the induced current? (Express your answer to two significant figures.)
