The moment of inertia of a thin disc about axes \( a, b, c, d \) are \( I_1, I_2, I_3 \) and \( I_4 \) respectively, as shown in figure. If the moment of inertia about an axis passing through the centre and perpendicular to the plane of the disc is I then,

A uniform rod AB is suspended from a point P, at a variable distance x, from A, as shown in figure. To make the rod horizontal, a mass 'm' is suspended from its end A. Which set of variables will give a straight line when they are plotted?
