A triangular wire frame (each side = 2 m) is placed in a region of time variant magnetic field dB/dt=3T/s. The magnetic field is perpendicular to the plane of the triangle and its centre coincides with the centre of triangle. The base of the triangle AB has a resistance 1Ω while the other two sides have resistance 2Ω each. The magnitude of potential difference between the points A and B will be
