A force F is needed to hold a block of mass m stationary on an incline as shown in the diagram (see above). The plane has an angle of 0 with the horizontal and F is perpendicular to the inclined plane. If the coefficient of friction between the plane and the block is . What minimum force, F, is necessary to keep the block at rest? (A) (mg cose) (B) (mg sine) Reasoning: MaT (A) (C) (mg sine)/ (D) [mg (sine- cose)]/ 081(0) sasani abnege (C) it ci ntally to
