If I1 is the moment of inertia of a thin rod about an axis perpendicular to its length and passing through its centre of mas and I2 is the moment of inertia of the ring about an axis perpendicular to plane of ring and passing through its centre formed by bending the rod, then

A thin rod of length 4l mass 4 m is bent at the point as shown in the figure. What is the moment of inertia of the rod about the axis passing through O and perpendicular to the plane of the paper?
