The two +q along y axis and the two +3q charges will cancel the effect of its partner.
The distance from center to the middle left +q charge and that of middle right -2q charge is d. The field due to both is in same directions i.e from +q to - 2q. Find it using coulomb's law.
The distance from center to the lower left +5q charge and that of upper right -5q charge is 1.4d. The field due to both is in same directions i.e from +5q to - 5q. Find it using coulomb's law.
