SUMMARY
The discussion centers on calculating the electric force between an electron and a potassium nucleus using Coulomb's Law. The formula applied is Felectric = Kc[(q1)(q2)/r²], where Kc is 8.99 x 10⁹ N*m²/C², q1 is the charge of the potassium nucleus (19e), and q2 is the charge of the electron (-1.6 x 10⁻¹⁹ C). The calculated electric force is -1.62 x 10⁻⁸ N, indicating an attractive force between the negatively charged electron and the positively charged nucleus.
