Question

To analyze the experiment used to determine the properties of an electron.

In 1909, Robert Millikan performed an experiment involving tiny, charged drops of oil. The drops were charged because they had picked up extra electrons. Millikan was able to measure the charge on each drop in coulombs. Here is an example of what his data may have looked like.

Drop	Charge (C)
A	3.20×10−19
B	4.80×10−19
C	8.00×10−19
D	9.60×10−19

In Millikan's experiment, the charge on each drop of oil was measured in coulombs. Imagine the same experiment, but with charges measured in a fictitious unit called a zeet (Z).

Drop	Charge (Z)
A	1.77×10−14
B	4.13×10−14
C	4.72×10−14
D	5.31×10−14
E	7.67×10−14

What is the charge on an electron in zeets?

Answer 1

It is well documented that the charge on an electron is 1.602 x 10^-19 coulombs

Now in the data provided

We have straight correlation between the actual value in coulombs and the value in the fictitious unit Zeet.

We can use the trend function in excel to define the trend between the coulombic value and the Zeet value and then using this correlation calculate the new value of an electron in Zeet.

The excel result is shown

The value of an electron in Zeet would be 1.68 x 10^-14
