The figure shows a uniform rod lying along the `x`-axis. The locus of all the points lying on the `xy`-plane, about which the moment of inearth, of the rod is same as that about `O`, is

The figure shows a uniform rod lying along the X-axis. The locus of all the points lying on the XY-plane, about which the moment of inertia of the rod is same as that about O is

The figure shows a uniform rod lying along the x -axis. The locus of all the points lying on the x-y plane, about which the moment of inertia of the rod is same as that about O , is

The locus of all the points on theX- Y plane, about which the moment of inertia of the rod along an axis parallel to z axis is same as that about O is [The rod is lying inXZplane]:

Locus of all the points in a plane on which the moment of inertia about all mutually parallel axes of a rigid body is same throughout is

Locus of all the points in a plane on which the moment of inertia about all mutually parallel axes of a rigid body is same throughout is

A uniform rod of mass m and length L lies on the x-axis with its centre of mass at the origin. The locus of the point P in the x-y plane, such that moment of intertia of the rod about an axis parallel to the Z axis passing through P remains constant, is

The adjoining figure shows a disc of mass M and radius R lying in the X-Y plane with its centre on X - axis at a distance a from the origin. Then the moment of inertia of the disc about the X-axis is

A uniform thin rod is bent in the form of closed loop ABCDEFA as shown in the figure. The ratio of moment of inertia of the loop about x -axis to that about y -axis is
