A small conducting loop of mass m,radius r,resistance R is released from rest along a smooth inclined plane such that the plane of the loop is perpendicular to a magnetic field which varies along x-axis as B=B'(1+ax).here B' and a are constants.Find the speed of the ring as a function of time.

My problem is that we have to consider both 1)motional emf and 2)emf due to variable magnetic field.
how do u go about solving it?

The motional emf is induced across the inner 7 outer circumference & since the thickness of the ring is neligible, It can be neglected.
