Question

Experiments carried out by Robert Millikan in 1910-1913 determined the charge of an electron. In his experiment, oil droplets are charged when sprayed into a chamber. He then studied the motion of the charged oil droplets in a uniform electric field. He found that the following measured value of charge appeared on the oil droplets:

Drop	Charge (10-19 C)
1	13.13
2	6.563
3	19.71
4	22.89
5	16.48
6	8.204
7	11.50
8	26.13
9	18.08

What value of the elementary charge can be deduced from the above data? Show work.
