5. Consider the system pictured in Figure P19.21. A 15-cm length of conductor of mass15 g, free to move vertically, is placed between two thin, vertical conductors, and auniform magnetic field acts perpendicular to the page. When a 5.0-A current is directedas shown in the figure, the horizontal wire moves upward at constant velocity in thepresence of gravity.-15 cm-5.0 A5.0 AT5.0 AFigure P19.21 (a) What forces act on the horizontal wire, and under what condition is the wire ableto move upward at constant velocity?(b) Find the magnitude and direction of the minimum magnetic field required to movethe wire at constant speed.(c) What happens if the magnetic field exceeds this minimum value? (The wire slideswithout friction on the two vertical conductors.)
