- 1. Multiple Choice
The moment of inertia of a thin uniform rod about an
axis passing through its centre and perpendicular to
its length is . What is the M.I. about an axis through
one end and ⊥ the rod ? - 2. Multiple Choice
Two rings of the same mass and radius are placed such
that their centres are at a common point and their planes
are perpendicular to each other. The moment of inertia
of the system about an axis passing through the centre
and perpendicular to the plane of one of the rings is
(Take M = mass of each ring and R = radius of each
ring)

- 5. Multiple Choice
One quarter sector is cut from a uniform circular disc of radius R. This sector has mass M. It is made to rotate about a line perpendicular to its plane and passing through the centre of the original disc. Its moment of inertia about the axis of rotation as shown is
- 6. Multiple Choice
Two uniform, thin identical rods each of mass M and length I are joined together to form a cross. What will be the moment of inertia of the cross about an axis passing through the point at which the two rods are joined and perpendicular to the plane of the cross?
