YA a В b A conducting rod Jab| slides without friction on a conducting long enough parallel rails with separation distance L = 2m. connected through a resistor R = 20 A non-uniform magnetic field is applied Left ends of the rails are %3D perpendicular of the plane of the rails. The magnetic field is given as B= -2xk (T) where xis the distance from the origin along the x-axis. The rod moves with a constant velocity ü= 3î() under the effect of the extemal %3D %3D force F in the +x direction. Find the work-done by the external force on the rod while moving from x = 5m to x = 6m. a) 152 Joule b) 296 Joule c) 488 Joule d) 728 Joule e) 1016 Joule
