Transcribed Image Text:a zero-resistance rod
37. Predict/Calculate FIGURE 23-42 shows
sliding to the right on two zero-resistance rails separated by the
distance L = 0.500 m. The rails are connected by a 10.0-N resis-
tor, and the entire system is in a uniform magnetic field with a
magnitude of 0.750 T. (a) Find the speed at which the bar must be
moved to produce a current of 0.175 A in the resistor. (b) Would
your answer to part (a) change if the bar was moving to the left
instead of to the right? Explain.
