SUMMARY
The discussion centers on calculating the electric repulsion force between two small spheres, each with a deficit of 1.0 x 10^8 electrons, positioned 1.0 m apart. The correct force of electric repulsion, as confirmed by the textbook, is 2.3 x 10^-12 N. The calculation utilizes Coulomb's law, where the charge of each sphere is derived from the charge of a single electron (1.602 x 10^-19 C). The constant k, valued at 9 x 10^9 N m²/C², is essential for determining the force between the charged spheres.
