5 A 2 m long metallic rod rotates with an angular frequency of 200 rad s 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 a 100 V c 300 V b 200 V d 400 V
