Calculate the magnitude of the electric field at point P with the superposition principle. y P d X -q Data: q = 30.0 nC, d = 2.80 mm and P is at x = 56.0 mm. 6.41x10^7N/C 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 3/99 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 Tries 0/99
