Question 5

(17%) Problem 5: A rod with negligible resistance is sliding toward the right with a speed of 4.22 m/s on rails separated by L = 2.88 cm that have negligible resistance. A uniform magnetic field of 0.75 T, perpendicular to and directed out of the screen, exists throughout the region. The rails are connected on the left end by a resistor with resistance equal to 5.5 0. R & 33% Part (a) What is the magnitude, in amperes, of the induced current that passes through the resistor?
