1. The problem statement, all variables and given/known data 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=37.0 nanoCoulombs, d=4.60mm and P at x=92.0mm. 2. Relevant equations E = kQ/r^2 a^2 + b^2 = c^2 sin = o/h 3. The attempt at a solution I tried to solve this like a normal E field question. For the +q charge, I got that the E field would be: ( k * -37E-6 (sin2) / .092^2) + ( k * 37E-6 (cos2) and For the -q charge, I got that the E field would be: ( ( k * -37E-6 (sin2) / .092^2) - ( k * 37E-6 (cos2) This came out to 2740 N/C (positive b/c it asks for magnitude) but that was wrong. Can someone tell me where I'm going wrong? I attached the diagram.
