A solid cylinder of mass M and radius R pure rolls on a rough surface

1.	A solid cylinder of mass M and radius R pure rolls on a rough surface as shown in the figure. Choose the correct alternative (s).
Answer» The acceleration of the centre of mass is `F/(M)` The acceleration of the centre of mass is `(2)/(3)F/(M)` The FRICTION force on the cylinder acts backward The MAGNITUDE of the friction force is `F/(3)` Answer :B::C::D
