A certain electric dipole consists of charges

and

separated by a distance

and oriented along the

axis. An evaluation point is a distance

from the dipole center in the

direction, as shown in the figure. Assume that the evaluation point is very far from the dipole, .e.,

. Derive an expression for the magnitude

of the electric field of the dipole at at the evaluation point. Enter your answer in terms of

, and rational and

exact irrational numbers.
