Add a third force that will cause the object to remain at rest. Label the new force 13:3 . (gure 1) shows two forces acting on an object at rest. Draw the vector starting at the black dot. The location, orientation, and length of the vector will be graded. You can move the vectors F1 and F2 to construct the required vector, but be sure to return them into their initial positions before submitting the answer.
