A conducting rod with length 0.237 m , mass 0.150 kg , and resistance 75.8 Ω moves without friction on metal rails . A uniform magnetic field with magnitude 1.50 T is directed into the plane of the figure. The rod is initially at rest, and then a constant force with magnitude 1.90 N and directed to the right is applied to the bar.How many seconds after the force is applied does the bar reach a speed of 22.7 m/s ?
