Question 3. A block of mass m rests on a frictionless incline. Normally, the block would slide down, but a horizontal force F acts on the block to keep it from moving. M (a) Draw an FBD for the block (b) What magnitude for F will keep the block from sliding? (c) Using your answer from part (b), what is the normal force in terms of m, g, and o?
