Question

how many number of electrons constitute 2C of charge.find it?

Answer 1

Answer:

One electron = 1.6 × 10^-19 . 6.25 × 10^18 electrons.

Therefore 2 coulombs of charge has 12.5 × 10^18 = 1.25 × 10^19 electrons.

Answer 2

Number of electron is $12.5\times 10^{18}$

Given-Charge is $2C$

Find the number of electrons.

The electron is a subatomic particle whose electric charge is negative one elementary charge. Electrons belong to the first generation of the lepton particle family, and are generally thought to be elementary particles because they have no known components or substructure.

Coulomb force, also called electrostatic force or Coulomb interaction, attraction or repulsion of particles or objects because of their electric charge.

Now

Charge $q=ne\\n=\frac{q}{e}$

$n=\frac{2}{1.6\times 10^{-9}}$

$n=12.5\times 10^{18}$

Hence, the number of electrons is $12.5\times 10^{18}$
