Two parallel wires AL and KM placed at a...

Two parallel wires AL and KM placed at a distance I are connected by a resistor R and placed in a magnetic field B which is perpendicular to the plane containing the wire as shown in figure-5.340. Another wire CD now connects the two wires perpendicularly and made to slide with velocity v. Calculate the workdone needed to slide the wire CD. Neglect the resistance of all the wires.
