Question

What is the charge value of 45 electrons

Answer 1

`7.2* 10^(-18)C`

Step-by-step explanation:

-Let x be the charge of 45 electrons

-An electron has a relatively law mas.

-Using the law of proportions, the charge value of 45 electrons is calculated as:

`1e=1.6 * 10^(-19) coulomb\\45e=x\\\\x=(45*1.6 * 10^(-19) coulomb)/(1e)\\\\x=7.2* 10^(-18)C`

Hence, the electron charge of 45 electrons is
`7.2* 10^(-18)C`
