The Millikan Oil Drop Experiment

CHEM-CWBFQI

You decide you want to repeat Millikan's famous oil drop experiment to determine for yourself the charge on the electron.

Your final data is shown below:

Droplet #             Charge ($\text{C}$)            
1 $8.0 \times 10^{-19}$
2 $1.76 \times 10^{-18}$
3 $2.40 \times 10^{-18}$
4 $1.44 \times 10^{-18}$
5 $9.6 \times 10^{-18}$
6 $9.6 \times 10^{-18}$
7 $1.28 \times 10^{-18}$



From your data, what is the charge of an electron?
