What is electric force?. Coulomb’s law. 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. . Physics 2415 Lecture 6.

Particles dispersed in liquid media may become charged mainly in one of two ways :. The first involve selective adsorption of a particular ionic species present in solution.. Second : charges on particles arises from ionization of groups (such as COOH) that may be situated at the surface of the particles.. Assistant Professor. Department of Chemistry. Hajee. . Karutha. .
