Answer:
Number of electrons, [tex]n=5.56\times 10^{10}[/tex]
Explanation:
Given that,
Charge on the fur, [tex]q=8.9\ nC=8.9\times 10^{-9}\ C[/tex]
A piece of amber is charged by rubbing with a piece of fur. We need to find the electrons were added to the amber. It can be calculated using the quantization of charge as
q = n × e
Where
n is the number of electrons
e is the charge on electron
[tex]n=\dfrac{q}{e}[/tex]
[tex]n=\dfrac{8.9\times 10^{-9}}{1.6\times 10^{-19}}[/tex]
[tex]n=5.56\times 10^{10}\ electrons[/tex]
So, [tex]n=5.56\times 10^{10}\ electrons[/tex] number of electrons are added to the amber. Therefore, this is the required solution.
The number of electrons should be added to the amber which is charged by rubbing with a piece of fur is 5.56×10¹⁰ electrons.
What is the charge of an electron?
An electron is the negatively charged particle. The charge on an electron is given as,
[tex]e=1.6\times10^{-19}\rm C[/tex]
Here, the piece of amber is charged by rubbing with a piece of fur. The net excess charge on the fur is 8.9 nC ( 8.9 10-9 C), when it is rubbed.
Let suppose there is n number of electron to be added to the amber. As the charged of an electron is [tex]1.6\times10^{-19}\rm C[/tex].
Thus, the product of the number of required electron and the charge of one electron will be equal to the net excess charge on the fur.
[tex]8.9\times10^{-9}=n\times1.6\times10^{-19}\\n=5.56\times10^10[/tex]
Hence, the number of electrons were added to the amber which is charged by rubbing with a piece of fur is 5.56×10¹⁰ electrons.
