A ring is in a region of space that contains a uniform magnetic field directed perpendicular to the plane of the ring. The radius of the ring is 0.3 m. Over the time interval from t = 0 to t = 0.9 s, the magnetic field changed linearly as shown in the figure. B1 = 26 T and B2 = 2 T. What is the magnitude of the electric field (unit in V/m) along the perimeter of the ring during this time interval? B1 B (T) 0 B2
