An electric dipole consists of two electric charges of equal magnitude and opposite sign. If the charges areĀ qĀ and āqĀ and are located at a distanceĀ dĀ from each other, then the electric fieldĀ EĀ at the pointĀ P in the figure is .Ā
Ā
By expanding this expression forĀ EĀ as a series in powers ofĀ d/D, show thatĀ EĀ is approximately proportional to 1/D3Ā whenĀ PĀ is far away from the dipole.
