A conducting rod of length L moves on two horizontal frictionless rails, as in F

Question

A conducting rod of length L moves on two horizontal frictionless rails, as in Figure P20.18. A constant force of magnitude 1.70 N moves the bar at a uniform speed of 2.10 m/s through a magnetic field B that is into the page.

(a) What is the current in an 14.00 ? resistor R?
