The figure below shows a box with a mass of m = 3.50 kg on a surface inclined at an angle of 35.0°. The coefficient of static friction between the box and the surface is 0.250. Find the minimum magnitude of the force F (in N), applied to the box in a direction perpendicular to the surface, that will prevent the box from sliding down the surface.
