Which of the following statements about friction is FALSE? A Friction force is always less than the force required to prevent motion. B) The total frictional force is dependent on the area of contact between the two surfaces. The direction of frictional force on a surface is such as to oppose the tendency of one surface to slide relative to the other. The magnitude of the frictional force is equal to the force which tends to move the body till the limiting value is D reached.

A skier stands on a 5° slope. If the coefficient of static friction is 0.1, does the skier start to slide down?
