## Passage

Consider a cylinder of mass M = 1 kg and radius R = 1 m lying on a rough horizontal plane. It has a plank lying on its top as shown in the figure. Cylinder of Mass 1 Kg and Radius 1 Meter on the Sphere in above fig cylinder of m = 1kg on the sphere of radius R.

A force F = 35 N is applied on the plank such that the plank moves and causes the cylinder to roll. The plank always remains horizontal. There is no slipping at any point of contact.
