NaCl molecule is bound due to the electric force between the sodium and the chlorine ions when one electron of sodium if transferred to chlorine. Taking the separation between the ions to be 2.75×10^(-8) cm, find the force of attraction between them. State the assumptions (if any) that you have made.
