For a body of mass “m” on a rough inclined plane with a constant but arbitrary coefficient of friction as shown in the figure, what is the acceleration on the inclined plane if the net downward force is donated as “F”. Let “g” be the acceleration due to gravity and “u” be the coefficient of friction.

• A. g x sin θ
• B. g x cos θ
• C. g (sin θ – u cos θ)
• D. g (cos θ – u sin θ)
