The symbol . k. is a proportionality constant known as the Coulomb's law constant. The value of this constant is dependent upon the medium that the charged objects are immersed in. In the case of air, the value is approximately 9.0 x 10^9 N • m^2 / C^2. . © 2014 Pearson Education, Inc.. Contents of Chapter 16. Static Electricity; Electric Charge and Its Conservation. Electric .
