A 1 m long metallic rod is rotated with angular frequency of 400 rad s -1 about an axis normal to the rod passing through one of its end. The other end of the rod is in contact with a circular metallic ring. A constant and uniform magnetic field of 0.5 T parallel to axis exist everywhere. The emf induced between centre and ring is

Q. A $1 m$ long metallic rod is rotated with angular frequency of $400 r a d s^{- 1}$ about an axis normal to the rod passing through one of its end. The other end of the rod is in contact with a circular metallic ring. A constant and uniform magnetic field of $0.5 T$ parallel to axis exist everywhere. The emf induced between centre and ring is
