SUMMARY
The discussion centers on calculating the electrostatic force of attraction between Ca2+ and O2- ions separated by 1.25 nm using Coulomb's Law. The correct approach involves using the elementary charge (approximately 1.602 x 10-19 C) multiplied by the respective charges of the ions, which are +2 for Ca2+ and -2 for O2-. This results in a force calculation that accurately reflects the interaction between these ions.
