A 2 m long metallic rod rotates with an angular frequency of 200 rad s–1 about an axis normal to the rod passing through its one end. The other end of the rod is in contact with a circular metallic ring. A constant magnetic field of 0.5 T parallel to the axis exists everywhere. The emf developed between the centre and the ring is
- 100 V
- 200 V
- 300 V
- 400 V
Answer
(A) 100 V
