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. y P +q P Data: q = 32.0 nC, d = 4.80 mm and P is at x = 96.0 mm. By the principle of linear superposition, the total electric field at position P is the vector sum of the electric field contribution from charges +Q and -Q. Submit Answer Incorrect. Tries 4/99 Previous Tries In the previous problem, 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 magnitude of the electric field at point P with this approximation and the same values for Q, d and x as in the previous problem. Submit Answer Incorrect. Tries 4/99 Previous Tries -q
