Question

What is the total charge of 20 electrons in zeka-Coulombs?

Answer 1

Answer:

$3.2\times 10^{-18}\ C$

Explanation:

No of electrons, n = 20

We need to find the total charge. We can use quantization of electric charge in this case.

Net charge,

q = ne

e is charge on an electron

$q=20\times 1.6\times 10^{-19}\\\\q=3.2\times 10^{-18}\ C$

So, there are $3.2\times 10^{-18}\ C$ of charge in 20 electrons.
