Three point-like charges are placed at the corners of an equilateral triangle as shown in the figure. Each side of the triangle has a length of 20.0 cm, and the point (A) is located half way between q1 and q2 along the side. Find the magnitude of the electric field at point (A). Let q1=-1.30 µC, q2=-4.20µC, and q3= +4.30 µC.
