Exercise 1: Five forces Fi, Fa,.... have equal magnitude F and point towards the ver- tices of a pentagon as in Figure 8(c), Follow the steps below to show that these five forces cancel each other. 1. Place one of the forces (say force F) along the positive r-axis.\f2. Calculate the angle that two consecutive forces make with each other. Show your work belowExercise 2: Prove graphically that when six forces of equal magnitude point towards the vertices of an hexagon, they cancel each other
