The required number of electrons to make up the given magnitude of the charge is [tex]2.0 \times 10^{14}[/tex].
An electron is a subatomic particle that is bounded to the nuclei of an atom on the account of electrostatic forces due to other charged entities.
Given data -
The magnitude of the charge is, [tex]q = - 30 \;\rm \mu C = -30 \times 10^{-6} \;\rm C[/tex].
The standard magnitude of the charge on an electron is, [tex]e = -1.6 \times 10^{-19} \;\rm C[/tex].
And the standard expression for the number of electrons on any charged entity is,
n = q/e
Solving as,
[tex]n = -30 \times 10^{-6} / -1.6 \times 10^{-19}\\\\n \approx 2.0 \times 10^{14}[/tex]
Thus, we can conclude that the required number of electrons to make up the given magnitude of the charge is [tex]2.0 \times 10^{14}[/tex].
