consider an eletric dipole composed of two point charges +q and -q (where q is greater than 0)located at a distance d apart along the x-axi, with the center of the dipole at x=0. use the binomial approximation to show that for x>>d, the electric field vector at a point along the x-axis has the magnitude E=2kqd/x to the third power
