Consider an electric dipole on the x-axis and centered at the origin. At a distance h = 19.3 cm along the positive x-axis, the magnitude of the electric field due to the electric dipole is given by , where q = 7.29 ĀµC and d = 3.00 cm. Find a distance perpendicular to the x-axis and measure from the origin at which the magnitude of the electric field is the same.

Calculate the magnitude of the electric field due to a dipole made up of a point charge of 10-19C at z=1m and -10-19C at z=-1m at the point z=100m. Is the dipole approximation used in the text valid at this distance? If so calculate the electric field due to the dipole at z=100m.

An electric dipole consists of two electric charges of equal magnitude and opposite sign. If the charges areĀ qĀ and āˆ’qĀ 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.
