The moment of inertia of a uniform circular disc of radius 'R' and mass 'M' about an axis passing from the edge of the disc and normal to the disc is:

1. $\frac{1}{2}{\mathrm{MR}}^2$

2. $\frac{7}{2}{\mathrm{MR}}^2$

3. $\frac{3}{2}{\mathrm{MR}}^2$

4. ${\mathrm{MR}}^2$

The moment of inertia of the object depends upon:
1. distribution of mass 
2. axis of rotation of the body
3. shape and size of the body
4. all of the above

The ratio of the radii of gyration of a circular disc to that of a circular ring, each of same mass and radius, around their respective axes is -

1. $\sqrt{3}:\sqrt{2}$                                         2. $1:\sqrt{2}$

3. $\sqrt{2}:1$                                            4. $\sqrt{2}:\sqrt{3}$

The moment of inertia of a rod of mass M, length l about an axis perpendicular to it through one end is:

1.  ${\mathrm{Ml}}^2$

2.  $\frac{{\mathrm{Ml}}^2}{2}$

3.  $\frac{{\mathrm{Ml}}^2}{3}$

4.  Can't be determined

The moment of inertia of a uniform circular disc of radius 'R' and mass 'M' about an axis touching the disc at its edge and normal to the disc is :

(1) $\frac{3}{2}M{R}^2$

(2) $\frac{1}{2}M{R}^2$

(3) $M{R}^2$

(4) $\frac{2}{5}M{R}^2$

A light rod of length l has two masses m₁ and m₂ attached to its two ends. The moment of inertia of the system about an axis perpendicular to the rod and passing through the centre of mass is:

1.  $\frac{{\mathrm{m}}_1{\mathrm{m}}_2}{{\mathrm{m}}_1+{\mathrm{m}}_2}{l}^2$

2.  $\frac{{\mathrm{m}}_1+{\mathrm{m}}_2}{{\mathrm{m}}_1{\mathrm{m}}_2}{l}^2$

3.  $\left({\mathrm{m}}_1+{\mathrm{m}}_2\right)l^2$

4.  $\sqrt{{\mathrm{m}}_1+{\mathrm{m}}_2}<mspace\; width="1em"></mspace>l^2$
