 (where r is length of the square) but different directions. If you add up the vectors then they will add up to 0.\frac{kq}{(r^{2}/2)}Assuming by intensity you mean electric field intensity.If you draw the electric field vectors for the centre of the square you will find that all vectors have equal magitude=
 
Hence electric field at the center of the square is 0.
