wow What stupid mistake! Thank you both! ^_____^

Sorry, I don't understand, are you saying about the equation using the pythagorean theorem? If that is the case, here is how I did: AB² + CD² = AD² a² + a² = AD² a*root 2 = AD Ead² + Edb² = Ed² (kq/a*root 2)² + (kq/a*root 2)² = Ed² 2[(kq)²/2a²] = Ed² kq/a = Ed

As I said, I got by doing the addition of the vectors from A to D (force line from charge q+) and from D to B (force line from charge q-), I did that because the final vector will be the electric field at point D (Ed), using the pythagorean theorem (it is a right triangle, because DC and AB are...

Homework Statement Question 2.2 http://www.studyjapan.go.jp/en/toj/pdf/08-007.pdf The picture is in the next page of the problem. k is the Coulomb constant. q+ is the charge at point A. q- is the charge at point B. AC = BC = CD = a Homework Equations E = kq/d² a² = b² + c²...
