Moment of inertia depends on the axis of rotation and not on the
object.so it is not the same for all the objects I =Mr^2 if where M
is the mass and r s the distance from the axis .If you look at all
three objects Axis 1 has less mass with less distance from axis
.Most of the mass is lying on the axis of rotation .so axis 1 has
the smallest moment of inertia .Now comparing axis 2 and axis
3,Axis 3 has more distributed at a distance away from the axis so
axis 3 has more amount of inertia than axis 2 .Putting in order of
increasing it is axis 1>axis 2>axis 3 .Option (a)

The L-shaped object in the figure can be rotated in one of the following three ways: case 1, rotation about the x axis; case 2, rotation about the y axis; and case 3, rotation about the z axis (which passes through the origin perpendicular to the plane of the figure.) Rank these three cases in order of decreasing moment of inertia. Rank from largest to smallest. To rank items as equivalent, overlap them.
