A wire of length 2m is moving at a speed `2ms^(-1)` keep its length perpendicular to uniform magnetic field of 0.5 T. The resistance of circuit joined with this wire is `6Omega`. The rate at which wolrk is being done to keep the wire moving at constant speed is ..........
Options:
(a) `1/3` ω
(b) `2/3 ω`
(c) `1/6 ω`
(d) `2omega`
