9. Three point-like charges are placed at the following points on the x-y system coordinates (91 is fixed at x = -1.00 cm, q2 is fixed at y = +1.00 cm, and q3 is fixed at x = +3.00 cm. Find the magnitude of the electric force on the charge q2. Let q1 = -1.40 C, q2 = -3.80 C, and q3 +5.20 C. N = y(cm) +3 +2 +1 x(cm) +1 +2 +3 -1 -2 -3
