Question:

Millikan measured the charge of the electron in electrostatic units, esu. The data that he collected included the following series of charges found on oil drops: 9.60 * 10-10 esu, 1.92 * 10-9 esu, 2.40 * 10-9 esu, 2.88 * 10-9 esu, and 4.80 * 10-9 esu. 

(a) From this series, find the likely charge on the electron in electrostatic units.

(b) Predict the number of electrons on an oil drop with the charge 6.72 * 10-9 esu.

(c) The actual charge (in coulombs) of an electron is 1.602 * 10-19 C. What is the relation between esu and coulombs?
