A metallic ring of mass m and radius i (...

A metallic ring of mass m and radius i (ring being horizontal) is falling under gravity in a region having a magnetic field . If z is the vertical direction, the z- component of magnetic field is `B_z = B_0(1 + lambda z)` If R is the resistance of the ring and if the ring falls with a velocity v, find the power lost in the resistance . If the ring has reached a constant velocity, use the conservation of energy to determine v in terms of m,` B , lambda` and acceleration due to gravity g.
