Answer : The number of electrons it acquired is, [tex]11.875\times 10^{13}[/tex] electrons
Solution : Given,
Total charge = [tex]-19\mu C=-19\times 10^{-6}C[/tex] [tex](1\mu C=10^{-6}C)[/tex]
Charge on one electron = [tex]-1.60\times 10^{-19}C[/tex]
Formula used :
[tex]\text{Number of electrons}=\frac{\text{Total charge}}{\text{Charge on one electron}}[/tex]
Now put all the given values in this formula, we get the number of electrons.
[tex]\text{Number of electrons}=\frac{\text{Total charge}}{\text{Charge on one electron}}=\frac{-19\times 10^{-6}C}{-1.60\times 10^{-19}C}=11.875\times 10^{13}electrons[/tex]
Therefore, the number of electrons it acquired is, [tex]11.875\times 10^{13}[/tex] electrons.
