Problem 4SAQ

A student re-creates the Millikan oil drop experiment and tabulates the relative charges of the oil drops in terms of a constant, a .

What charge for the electron (in terms of a) is consistent with this data?

(a)

(b)

(c)

(d)

                                                              Step by Step Solution

Step 1 of 2

Millikan oil drop experiment:

Millikan's oil drop experiment proved that electric charge is quantized.  Millikan believed that there was a smallest unit of charge and he proved.

According to the millikan oil drop experiment charge on the oil drop can be calculated by the following formula.

Charge on the oil drop = A whole number  Charge on an electron.

It can be rearranged as follows.
