5. Consider the system pictured in Figure P19.21. A 15-cm length of conductor of mass
15 g, free to move vertically, is placed between two thin, vertical conductors, and a
uniform magnetic field acts perpendicular to the page. When a 5.0-A current is directed

The resistance of the lightbulb is R = 48.0 , assumed to be constant. The bar and rails have negligible resistance. The bar is moved toward the right by a constant force of magnitude F = 0.600 N.
