A block is resting on an incline. The angle of the incline (@) is increased slowly from zero until the point where motion begins. Which pair correctly states the mathematical relationship between the static friction force (Fs) and the angle () and the maximum static friction force (Fs-max) and the angle (0)? 1. Fs is directly proportional to sin 0 and Fs-max is independent of 0 2 Fs is directly proportional to cos 0 and Fs-max is independent of 0 Fs is directly proportional to sin 0 and Fs-max is directly proportional to cos e 4. Fs is directly proportional to cos B and Fs-max is directly proportional to cos 0 5 Fs is directly proportional to sin 0 and Fs-max is directly proportional to sin e 6 Fs is directly proportional to cos B and Fs-max is directly proportional to sin e
