Three point charges, A = 2.15 C, B = 6.80 C, and C= -4.10 C, 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 2.15 HC charge. N/C magnitude direction below the +x-axis (b) How would the electric field at that point be affected if the charge there were doubled? Would the magnitude of the electric force be affected? 60.0 Ajc 0.500 m CHC
