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 \( \mathrm{Na}^{+} \)ions and the green spheres represent \( \mathrm{Cl}^{-} \)ions. Consider only points \( \mathrm{A}, \mathrm{B}, \mathrm{C} \), 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 .
