Hi! could anyone help me to solve this problem please.
Three point charges are located at the corners of an equilateral triangle as in the figure below. Find the magnitude and direction of the net electric force on the 1.60 µC charge. (A = 1.60 µC, B = 7.20 µC, and C = -3.80 µC.)
magnitude ____ N
direction ____° counterclockwise from the +x-axis
