From a uniform disc of mass and radius a concentric disc of radius is cut out. For the remaining annular disc: is the moment of inertia about axis about ‘2’, about ‘3’ and about ‘4’. Axis ‘1’ and ‘2’ are perpendicular to the disc and ‘3’ and ‘4’ are in the plane of the disc
Axis’2’, ’3’ and ‘4’ intersect at a common point
