A wire of length 1 m is moving at a speed of 2ms–1 perpendicular to its length and a homogeneous magnetic field of 0.5 T. The ends of the wire are joined to a circuit of resistance 6 Ω. The rate at which work is being done to keep the wire moving at constant speed is
- \(\frac{1}{2} \mathrm{~W}\)
- \(\frac{1}{6} \mathrm{~W}\)
- \(\frac{1}{3} \mathrm{~W}\)
- 1W
Answer
(B) 1 6 ~W
