An electric dipole consists of two electric charges of equal magnitude and opposite signs. If the charges are and €“ q and are located at a distance from each other, then the electric field E at the point P in the figure is E = q/D2 €“ q (D + d)2 By expanding this expression for E as a series in powers of d/D, show that E is approximately proportional to 1/D3 when P is far away from the dipole.
