A dipole consists of two equal and opposite point charges (±q) separated by a distance d. (a)

Question:

A dipole consists of two equal and opposite point charges (±q) separated by a distance d.

(a) Write an expression for the electric field at a point (0, y) on the dipole axis. Specify the direction of the field in all four regions:

(b) At distant points (|y|>> d), write a simpler, approximate expression for the field. To what power of y is the field proportional? Does this conflict with Coulomb's law?
