When a honeybee flies through the air, it develops a charge of +20pc

When a honeybee flies through the air it develops a charge of +20pC. How many electrons did it lose in the process of acquiring this charge? Express answer as a number.

Answer

Total charge acquired

[latex]
+20 pC=20*10^{-12}C
[/latex]
Since the honeybee was neutral before, the total charge acquired would be equal to n*charge of an electron, where n is the number of electrons lost

charge on each electron

[latex]
1.6*10^{-19}C \\
n*1.6*10^{-19}=20*10^{-12} \\
n=12.5*10^{7}
[/latex]

Number of electrons lost

[latex]
n=12.5*10^{7}
[/latex]
