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.

What is the interaction responsible for holding the particles together is the same interaction that makes the toner stick to a copier drum and a balloon stick to your hair, as well as many other phenomena that we observe in our everyday world.. 4. . Two protons in an atomic nucleus are typically separated by a distance of 2 × 10. –. 15. m. The electric repulsion force between the protons is huge, but the attractive nuclear force is even stronger and keeps the nucleus from bursting apart. What is the magnitude of the electric force between two protons separated by 2.00 × 10. Was this a suitable solution to a major shift in thinking? . What role do paradigm shifts play in the progression of scientific knowledge?. Understandings:. Charge. Electric field. Coulomb’s law. Electric current.
