I was wondeirng if someone could help me figure out the solution for this problem\
A conducting rod of length (l) moves on two horizontal frictionless rails, as in Figure P20.18. A constant force of magnitude 7.00 N moves the bar at a uniform speed of 9.00 m/s through a magnetic field B that is directed into the page.
What is the current in an 9.00 resistor R?
What is the rate of energy dissipation in the resistor?
What is the mechanical power delivered by the constant force?
