A conducting rod with length 0.162 mm , mass 0.140 kgkg , and resistance 80.6 ?? moves without friction on metal rails as shown in the following figure(Figure 1). A uniform magnetic field with magnitude 1.50 TT is directed into the plane of the figure. The rod is initially at rest, and then a constant force with magnitude 1.90 NN and directed to the right is applied to the bar.
