A uniform disc of mass
m and radius
R rolls without slipping up a rough inclined plane at an angle of
30o with the horizontal. If the coefficient of static and kinetic friction are each equal to
μ and the forces acting on the disc are gravity and contact force, then find the direction and magnitude of the friction force acting on it.
