    First from symmetry considerations, you have that the electric field is directed along the line y=x. So you need only to compute the total Electric field in the origin: this is

    From the figure the charge Q is uniformly distributed on the cyan quarter circle, thus the linear density is . Thus the electric field is

    and the x component is .
