Question:

The arrangement of charges shown in FIGURE P25.68 is called a linear electric quadrupole. The positive charges are located at y = ±s. Notice that the net charge is zero. Find an expression for the electric potential on the y-axis at distances y W s. Give your answer in terms of the quadrupole moment, Q = 2qs².
