Explanation:
In the middle of the dipole, the electric fields contributed by both charges are in the same direction; they are both pointing toward the negative charge. Thus, the magnitude of the electric field is the sum of the contribution of the two charges.
The direction of the field is pointing to the negative charge. So its actual direction depends on how the dipole is oriented. If the dipole is oriented north-south and that the +q is the northern pole, then E is pointing to the south. That is,
