Match list I with list II and select the correct answer.

Statement – 1— A sphere and a cylinder slide without rolling from rest from the top of an inclined plane. They will reach the bottom with the same speed.
Statement – 2 — Bodies of all shapes, masses and sides slide down a plane with the same acceleration.

Statement – 1— Friction is necessary for a body to roll on surface
Statement – 2— Friction provides the necessary tangential force and torque.

Statement –1— A body tied to a string is moved in a circle with a uniform speed. If the string suddenly breaks the angular momentum of the body becomes zero.
Statement – 2 — The torque on the body equals to the rate of change of angular momentum.

Moment of inertia of a uniform circular disc about a diameter is I. Its moment of inertia about an axis perpendicular to its plane and passing through a point on its rim will be

A wheel of mass 10 kg has a moment of inertia of 160 kg-m² about its own axis, the radius of gyration will be

Moment of inertia of a thin circular disc of mass M and radius R about any diameter is

A 1 m long rod has a mass of 0.12 kg. What is the moment of inertia about an axis passing through the centre and perpendicular to the length of rod?

Two circular rings have their masses in the ratio of 1 : 2 and their diameters in the ratio of 2 : 1. The ratio of their moment of inertia is

If the external torque acting on a system τ = 0, then
