The attractive or repulsive interaction between any two charged objects is an . electric force. . . video. 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. . Electric Potential. QUIZ. Define electric force. What is charge measured in?. If two charges are opposite, what happens to those charges?. 4. The force between two charges can be calculated using the following equation . © 2014 Pearson Education, Inc.. Contents of Chapter 16.
