The electric field strength of a dipole in free space can be defined based on the dipole's moment and the distance from the dipole. An electric dipole consists of two equal and opposite charges separated by a distance \\(d\\). The dipole moment \\(p\\) is given by: \\\[ p = q \\cdot d \\\] where \\(q\\) is the magnitude of one of the charges.
