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 +q -q P x Data: q = 28.0 nC, d = 3.60 mm and P is at x = 72.0 mm. Submit Answer Unable to interpret units. Computer reads units as "deg". Tries 0/99 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
