A lamina is made by removing a small disc of diameter 2R from a bigger disc of uniform mass density and radius 2R as shown in the figure The moment of inertia of this lamina about axes passing through O and P is I and Ip respectively Both these axes are perpendicular to the plane of Ip the lamina The ratio to the nearest integer is Io 2R 2R P
