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
+20 pC=20*10^{-12}C
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
1.6*10^{-19}C \\ n*1.6*10^{-19}=20*10^{-12} \\ n=12.5*10^{7}Number of electrons lost
n=12.5*10^{7}
Your reaction
