In the image are three point charges, Q₁ = 21.4 µC, Q2 = -34.6 μC, and Q3 = 57.3 µC, arranged according to the figure. A fourth point charge is located at point A with a charge of QA = 13.5 µC. The charges form a square with height y of 30.1 cm and width x of 30.1 cm. Calculate the magnitude F of the net force on the charge at point A. *
