its questions 25 chapter 31, fromthe book physics for scientist and engineers with modern physicseight edition by serway. this is the question: Figure 31.25 shows a bar of mass m=0.200kg that can slide withoutfrictionon a pair or rails separated by a distance l=1.20 m andlocated on an inclined plane that makes an angle of 25degrees withrespect to the ground. The resistance of the resistor is R=1.00ohmsand a uniform magnetic field of magnitude B=0.500 T is directedownward, perpendicular to the ground, over the entire regionthrough which the bar moves. with what constant speed v does thebar slide along the rails?
