The surface of an ideal molecule of table salt (NaCl) is a square with a chemical structure as shown in the figure. The blue spheres represent Na ions and the green spheres represent Cl− ions. Consider only points A, B, C, and D. What is the magnitude of the net electrostatic force on the chlorine ion at point A due to the sodium ions at points B and C? Note: the bond length is 0.282 nm.
