Three point charges, A = 1.80 µC, B = 7.50 µC, and C = -3.80 µC, are located at the corners of an equilateral triangle as in the figure above. Find the magnitude and direction of the electric field at the position of the 1.80 µC charge. Each side is 0.5m and the angle at point A is 60 degrees, and charge B is used with cos60 and sin60. Find the magnitude (N/C) at point A, and the direction in degrees counterclockwise from the positive x-axis.
