The number of electrons taken out from a body to produce 1 coulomb of charge will be:
Correct answer: A. 6.25 x 10^18
- A. 6.25 x 10^18
- B. 625 x 10^18
- C. 6.023 x 10^23
- D. None of these
Explanation
We can simply find the number of electrons taken out from a body to produce 1 coulomb of charge by using the following formula: Q = ne (*)where 'Q' is the charge, 'n' is the number of electrons, and 'e' is the electronic charge.Charge 'Q' = 1 Coulombe = 1.6 * 10⁻¹⁹ CThen, using (*), we get 1 = n * 1.6 * 10⁻¹⁹ 1/1.6 * 10⁻¹⁹ = n 6.25 * 10¹⁸ = number oof electronsHence, 6.25 * 10¹⁸ number of electrons are taken out from a body to produce 1 coulomb of charge.

About Electrostatics
Electrostatics describes forces between charges through Coulomb's law, electric fields and field intensity, then uses electric potential to measure energy per unit charge. Capacitors store charge and electrical energy, with capacitance depending on geometry and dielectric material, not simply on the amount of charge present.
