Please open attached Which of the following gives the proper directions for the forces on charge q due to charges q1 and q2? F1 is the force on charge q due to charge q_1, and F_2 is the force on charge q due to charge q_2. Standard coordinates are being used (i.e., "left" is the negative x direction, and "right" is the positive x direction). This what I calculated:
F10=0.225N ( in the negative direction, so -0.225 N)
F20: 0.165 N ( in the positive direction)
