i saw the equation: (1/(4*pi*E))((Qq)/(a^2)) as the force on one of the sides of the square between Q and q. and i know there's another force pointing perpendicular on the adjacent side of the square. the addition of those two vectors would give me the hypotenuse of a 454590 triangle. therefore, i saw that the magnitude of the hypotenuse is that force times sqrt(2).
would that be right?
