The drawing shows a top view of a hockey puck as it slides across frictionless ice. Three forces act on the puck, and it is in equilibrium. The force F with arrow is applied at the center and has a magnitude of 20. N. The force F with arrow1 is applied at the top edge, and F with arrow2 is applied half way between the center and the bottom edge. Find the magnitude of F with arrow1 and F with arrow2.
