Linked Answer Q.27 & Q.28: A cylinder of mass, $m$, and radius, $r$, is rolling without slipping down an inclined plane that makes an angle, $\theta$, with the horizontal. The radius of gyration, $k$, of the cylinder is half the radius. (The coefficient of friction is, $\mu$; Acceleration due to gravity is, $g$). The frictional force acting on the cylinder is given by
- A. $\frac{1}{5}mg\sin\theta$
- B. $\frac{1}{2}mg\sin\theta$
- C. $\mu mg\sin\theta$
- D. $mg\sin\theta$
