In a circular region of radius R,  magnetic field is uniform and changes according to $B=kt$  where k  is a constant and  t is the time.  A conducting wire is bent to form a right angled triangular loop and kept perpendicular to the magnetic field with one corner at the centre O of the circle.  Match the magnitudes of emf generated between  different points.  Take  $OD=OC=\sqrt{3}R$ and  $\epsilon =K\pi R^2/4$. Neglect self- inductance of the loop.
