MEDIUM
IMPORTANT

A thin non-conducting ring of mass m, radius a carrying a charge q can rotate freely about its own axis which is vertical. At the initial moment, the ring was at rest in horizontal position and no magnetic field was present. At instant t=0, a uniform magnetic field is switched on which is vertically downward and increase with time according to the law B=B0t. Neglecting magnetism induced due to rotational motion of ring.

If the surface of a ring is perpendicular to Magnetic Field, then the magnitude of an electric field on the circumference of the ring is: (Take B0 and a as the magnetic field and the radius of ring)
