Four point charges \( + q, + q, - q\,{\rm{and}}\, - q\) are placed on the corners of a square of side length ‘\(a\)’ as shown in the figure. The magnitude of the electric field at a point which is at a distance \(x( > > a)\) from the centre along a line perpendicular to the plane of the square and passing through the centre is,
