Four positive charges are positioned in such a manner than they form a square with sides which are 5.0 cm long. A 3.0 μC charge is placed at the (0 cm, 0 cm) mark. A 9.0 μC charge is placed at the (0 cm, 5 cm) mark, a 3 μC charge is placed at the (5 cm, 5 cm) mark, and a 6.0 μC charge is placed at the (5 cm, 0cm) mark. Determine the magnitude and direction of the electric field at the exact center of the square.
