A wire loop of resistance

10 ohm and radius 10 cm is kept in the plane of this paper in a uniform magnetic field B.

The direction of B is perpendicular to the

plane of the page and points out of it and its magnitude is increasing at the rate of 0.50T/s.

Determine the magnitude and direction of the induced current in the loop.
