Starting from rest a cylindrical body of uniform density and mass m is allowed to roll down from the top of a fixed inclined plane of total height h The upper half of the inclined plane is rough and the friction coefficient is high enough to allow pure rolling and the 14gh lower half of the inclined plane is frictionless The velocity of the centre of the body upon arriving at the bottom of the plane is 9 If the moment of inertia of the body about its central axis is mk the ratio R is
