Two charges, +q and -q, are located in the x-y plane at points (0,+d/2) and (0,-d/2), respectively. Calculate the magnitude of the electric field at point P with the superposition principle.
Data:
q=40.0 nC,
d=4.60 mm
P at x=92.0 mm.
2.122×103 N/C
You are correct. Computer's answer now shown above.

In the previous part, you can get an approximate answer for the electric field at point P by using the electric dipole approximation which is valid for the limit x>>d. Calculate the electric field at point P with this approximation and the same values for q, d and x as in the previous problem.

Remember the approximation for a charge along the dipole axis. In the present case point P is in a plane perpendicular to the dipole axis. can someone help me with the second question?
