2. Atoms & Elements / Millikan Oil Drop Experiment / Problem 10
A scientist in a parallel universe performs the Millikan oil-drop experiment. The unit of charge in that universe is gallic (ga). He obtained the following data for four oil droplets (A, B, C, and D):
A 2.06×10–11 ga
B 2.75×10–11 ga
C 4.13×10–11 ga
D 5.50×10–11 ga
Using the charge of an electron as 6.88×10–12 ga, calculate the number of electrons on each drop.
