2. A cyclist applies a force F with magnitude F = 50N in the same direction as the vector b = 4 j. The distance between the pivot point (fulcrum) and the point of force impact is where r has the same magnitude as A B where A = (20, 15, 1) and B = (6,5, 0) but is in the opposite direction to A B. 2.1 The expression for F = qs i+q6j+** k 2.2 The expression for r =** i +** j+9₁k 2.3 The Moment of force is M = q8 i + ** j +q9k
