A disc is pulled by a force `F` acting at a point above the centre of mass of the disc.
The direction of frictional force `(f_r)` acting on disc pushed on a rough surface will be represented by.

In the following problems, indicate the correct direction of friction force acting on the cylinder, which is pulled on a rough surface by a constant force F . A cylinder is pulled horizontally by a force F acting at a point below the centre of mass of the cylinder, as shown in figure. The friction force can be given by which of the following diagrams. .

What are the forces acting on the disc?

A solid sphere of mass M and radius R is pulled by a force F as shown in figure . If the sphere does not slip over the surface , then frictional force acting on the sphere is

Consider a disc of mass m and radius R placed on a rough plank of mass M which is turn is place on a smooth horizontal surface. Now plank is pulled by a force F and disc starts to roll on the plank. If there is no friction any where then find (a) Fricition force acting on the disc (b) Angular acceleration of the disc
