Two identical point charges +Q are located on the y-axis at y=+d/2 and y=-d/2 and a third charge -2Q is located at the origin as shown in the Figure. The three charged +Q, +Q, and -2Q form an electrically neutral system called an electric quadrupole. A charge q is placed on the x-axis a distance x = d from the quadrupole. At what is the net force on q due to the quadrupole? Answer: +Q r 2Q F3 +Q F. 0 F1 Two identical point charges +Q are located on the y-axis at y=+d/2 and y=-d/2 and a third charge -2Q is located at the origin as shown in the Figure.
