Question

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?

Express your answer in zeets using two significant figures.
