A disc of circumference `s` is at rest at a point `A` on horizontal surface when a constant horizontal force begins, to act on its centre. Between `A` and `B` there is sufficient friction to prevent slipping and the surface is smooth It the right of `B, AB = s`. The disc moves from `A` to `B` in time `T`. To the right of `B`.

A

the angular acceleration of the disc will disappear, linear acceleration will remain unchanged

B

linear acceleration of the disc will increase

C

the disc will make one rotation in time T/2

D

the disc will cover a distance greater than s in a furthur time T

A force F is applied at the top of a ring of mass M and radius R placed on a rough horizontal surface as shown in figure. Friction is sufficient to prevent slipping. The friction force acting on the ring is:

A disc of radius R and mass M is under pure rolling under the action of a force F applied at the topmost point as shown in figure. There is sufficient friciton between the disc and the horizontal surface. The acceleration is given as

A sphere S rolls without slipping with a constant speed on a plank P . The friction between the upper surface of P and the sphere is sufficient to prevent slipping, while the lower surface of P is smooth and rest on the ground. Initially P is fixed on the ground by a pin N . If N is suddenly removed
