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 X -q Data q = 26.0 nc, d = 3.60 mm and P.is at x - 72.0 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. You have entered that answer before
