A circular ring of wire is placed in a time varying magnetic field B=B0t,where B means magnetic field and t means time.It's radius is R.At a distance of 1.732R from the centre a metallic rod of length 2R is fixed about it's end and it can rotate with angular speed .find the emf induced in the rod when it touches the near end of the ring???note::the magnetic field is only in the regionbounded by the ring and nowhere else outside.
