An electric dipole consists of charges +q_1 and -q_1 separated by 2 mm. find the magnitude of the electric dipole moment if q_1 = 5 pc? find the magnitude of the electric field due to the dipole at point p along the dipole axis at distance z = 5 m, where z is the distance from the center of the dipole to point p? draw the system, the dipole moment and the location of point p
