A solid cylinder of mass m and radius r is rolling on a rough inclined plane of inclination θ. The coefficient of friction between the cylinder and incline is µ. Then (A) frictional force is always µmg cos θ (B) friction is a dissipative force (C) by decreasing θ, frictional force decreases (D) friction opposes translation and supports rotation.
