# Problem: A chemist in an imaginary universe, where electrons have a different charge than they do in our universe, performs the Millikan oil drop experiment to measure the electrons charge. The charges of several drops are recorded below. What is the charge of the electron in this imaginary universe? Drop #ChargeA-6.6 10-19 CB-8.8 10-19 CC-11.0 10-19 CD-4.4 10-19 C
