Equal torques act on the discs A and B of the previous problem, initially both being at rest. At a later instant, the linear speeds of a point on the rim of A and another point on the rim of B are vA and vB, respectively. We have
(a) vA >vB
(b) vA = vB
(c) vA < vB
(d) the relation depends on the actual magnitude of the torques.
