What is the speed of the wire when pulled with 10 n -answer


A 8.0-cm-long wire is pulled along a U-shaped conducting rail in a perpendicular magnetic field. The total resistance of the wire and rail is 0.32 Ω. Pulling the wire with a force of 1.0 N causes 4.5 W of power to be dissipated in the circuit.
