A circular disc is rotating about its natural axis with angular velocity of 10 rad/s . A second disc of same mass is joined to it coaxially. If the radius of the second disc is half of the first one, then what is the angular velocity if they rotate together ?

A circular disc is rotating about its own axis, the direction of its angular momentum is

Two uniform circular discs having the same mass and the same thickness but different radii are made from different materials. The disc with the smaller rotational inertia is

A circular disc is rotating without friction about its natural axis with an angular velocity omega . Another circular disc of same material and thickness but half the raduis is gently placed over it coaxially. The angular velocity of composite disc will be

Initial angular velocity of a circular disc of mass M is omega_(1) . Then two small spheres of mass m are attached gently to two diametrically opposite points on the edge of the disc. What is the final angular velocity of the disc -

Initial angular velocity of a circular disc of mass M is omega_(1) . Then two small spheres of mass m are attached gently to two diametrically opposite points on the edge of the disc. What is the final angular velocity of the disc -

When a circular disc of radius 0.5 m is rotating about its own axis, then the direction of its angular momentum is

(A) : Moment of inertia of circular ring about a given axis is more than moment of inertia of the circular disc of same mass and same size, about the same axis. (R ) : All the mass of a ring is near its nm and the mass is distributed uniformly in case of disc.
