MAGNETIC INDUCTION PROBLEM.
An elasticized conducting band is around a spherical balloon.Its plane passes through the centre of the balloon.A uniform magnetic field of magnitude 0.04T is directed perpendicular to the plane of band.Air is let out of the balloon at 100 cubic centimetre per second at an instant when the radius of the balloon is 10 cm.what is the induced emf in band?
