1. The fundamental SI unit of charge, the Coulomb, is a very large amount of charge. Find the number of electrons you would have to gather to have 0.27 Coulombs. 2. Find the electromagnetic force exerted by that one Coulomb of electrons on one Coulomb of protons one meter away. 3. Finally, for comparison, find the gravitational force between those two bunches of particles. (show work) thank you.

1. If the charge on the electron is e = 1.6021176462 x 10^-19 C. Then in 1 coulomb ofcharge there will be: - number of electrons = 1/1.6021176462 x 10^-19Which is 6.241509745 x 10^18 electrons....
