Consider the arrangement of charges shown in the figure. Four charges of equal magnitude Q but varying sign are placed at the corners of a square as indicated. A positive charge q is placed in the center. What is the direction of the net force, if any, on the center charge? Indicate your answer by placing the appropriate label in the first box. Now Suppose that the charge q were to be displaced slightly from the center position. On the figure, label each box with the arrow that best indicates the direction of the net force that would act on q if it were moved to that location. Net Force +Q -Q Answer Bank no force 9 -Q +Q ↑
