Two parallel rails with negligible resistance are 10.0 cm apart and are connected by a 5.00 Ω resistor. The circuit also contains two metal rods having resistances of 10.0 Ω and 15.0 Ω sliding along the rails. The rods are pulled away from the resistor at constant speeds of 4.00 m/s and 2.00 m/s, respectively. A uniform magnetic field of magnitude 0.010 T is applied perpendicular to the plane of the rails. 


a) Determine the power dissipated in the 5.00-Ω resistor.

b) Determine the force in the 10 Ω rod in order for it to move at constant v.
