Three ropes pull on a knot that holds them together. Rope 1 exerts 20 N force in the positive x direction and rope 2 pulls with a 40 N force at an angle 53 degrees above the negative x axis. Rope 3 pulls with a force that balances the first two so that the net force on the knot is zero. Find the magnitude and direction of F3.
