is the one-electron Coulomb
From Yahoo Answers
Answers:If the charge on the electron is e = 1.6021176462 x 10^-19 C. Then in 1 coulomb of charge there will be: - number of electrons = 1/1.6021176462 x 10^-19 Which is 6.241509745 x 10^18 electrons. The force between two point charges q1 and q2, separated by a distance 'r' is given by Coulomb's law: - F = ...1 . q1.q2 ......__ . ____ ..... 4 0 . r Substituting values this equation becomes: - F = 10^-6 x 10^-6/(4 x 3.14 x 8.854 x 10^-12 x 0.2 ) Hence, F = 0.2247 N (rounded to 4 DP) (Using calculator constants for 0)
Answers:one electron is 1.60217646 10-19 C 1 coulomb is 6.242197253 * 10 ^ 18 electrons
Answers:Remember stoichiometry from chemistry? Set it up just like that. Mathematically, you divide -3.2E-8/-1.6E-19. -3.2E-8 c X (1 electron/ -1.6E-19 c)
Answers:It's always refreshing and rewarding to try to answer a question asked out of curiosity and wanting to get to know things. From what You wrote, I assume You're asking Yourself if all of the electrons are actually charged. All electrons are charged in exactly the same way, i.e. they carry what is known as "elementary charge" of 1.602 10^-19 C. Every electron carries this charge and it cannot change. How much an object is charged is due to excess electrons, compared to other charged particles, namely positively charged protons in atomic nuclei. Since matter is made of atoms, which contain protons in their nuclei and electrons in their orbits, an atom is generally neutral although it can contain many protons and electrons. But if a piece of material contains excess electrons, it will have a net negative charge. How much is this charge? If an object has 10 electrons more than protons, the excess charge will be 10*(1.602 10^-19 C). All the remaining electrons and protons cancel each other out in their charge, so You don't see the effect on a macroscopic object. If it has more electrons, You'll see the negative charge exerting force on other nearby charged objects, and if it has a lack of electrons (less electrons than protons), the object will have a net positive charge. Depending on how much electrons You remove or add, You'll create a more or less charged object. If You add circa 10^19 electrons, the object will become charged by approx. 1 coulomb of charge. So, a "coulomb" can be thought of as a measure of how many excess or lacking electrons are there in a macroscopic object, the electrons being "charge carriers". And the more electrons You want removed (or added), i.e. the more You want to charge an object, the more powerful generator You need for this, to act against the attractive forces that act between protons and electrons, trying to keep them together. To remove the first electron, Your generator needs to act against the Coulomb force of only one remaining excess proton in the object; after You've removed 10^6 electrons, when removing the next electron, Your generator needs to work against the force of 10^6 excess protons that remained, which exert a larger force on that electron. How much force? - that can be calculated from Coulomb's law.
