How many newtons are there in one coulomb of charge?
One coulomb is equal to the charge on 6.241 × 1018 protons. The charge on 1 proton is 1.6 × 10-19 C. Conversely, the charge of an electron is -1.6 × 10-19 C. A coulomb is an enormous charge - two 1 C charges that are 1 m apart exert a force of 9 × 109 newtons (see Coulomb's law)
