Use the information below to answer question 4. A block of wood on a horizontal surface may have two horizontal forces, F, and F2, acting on it. Either force may pull to the left or right. (The normal force and force due to gravity are equal in magnitude and opposite in direction and may be ignored for this exercise.) 4 . Complete the chart below by providing the missing force values and direction (i.e., left or right), and use vector arrows to draw the two forces, F, and F2, on the diagram.
