A certain electric dipole consists of charges ++q and −−q separated by distance ,d, oriented along the x-axisx-axis as shown in the figure. Find an expression for the magnitude of the electric field e of the dipole at a point far away in the y-direction, y-direction, a distance r away from the midpoint of the dipole. Assume that r is much greater than . D. Enter your answer in terms of ,q, ,d, ,r, and 0.
