The moment of inertia of a copper disc, rotating about an axis passing through its centre and perpendicular to its plane

A disc of radius 10 cm can rotate about an axis passing through its centre and perpendicular to its plane. A force of 10 N is applied along the tangent in the plane of the disc. If the moment of inertia of the disc about its centre is 5 kg m2, then the increase in the angular velocity of the disc in 10 s will be

A disc of radius 10 cm can rotate about an axis passing through its centre and perpendicular to its plane. A force of 10 N is applied along the tangent in the plane of the disc. If the moment of inertia of the disc about its centre is 5 kg m^(2) , then the increase in the angular velocity of the disc in 10 s will be

A circular disc of mass 10 kg and radious 0.2 m is set into rotation about an axis passing through its centre and perpendicular to its plane by applying torque 10 Nm. Calculate angular velocity of the disc that it will attain at the end of 6 s from the rest.

A uniform disc of radius R and mass M can rotate on a smooth axis passing through its centre and perpendicular to its plane. A force F is applied on its rim. See fig. What is the tangential acceleration

A disc of mass 4 kg and radius 0.2 m, makes 20 rev/s, about an axis passing through its centre and perpendicular to the plane of the disc. The angular momentum of the disc is approximately equal to
