Oil Drop Experiment

Q. A single electron has a charge of 5.1x10^-15 Z. Using zeets and a fictitious unit of mass called wiggle, w, the charge-to-mass ratio of an electron is 2.4x10^6 Z/w. What is the mass of an electron in wiggles using two significant figures.

Oil Drop Experiment

Q. In Milikan'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). What is the charge on an electron in zeets? Express your answer in zeets using two significant figures.

Oil Drop Experiment

Q. To analyze the experiment used to determine the properties of an electron. In 1909, Robert Milikan performed an experiment involving tiny, charged drops of oil. The drops were charged because they had picked up extra electrons. Millikan was able to measure the charge on each drop in coulombs. Here is an example of what his data may have looked like. Based on the given data, how many extra electrons did group C contain?
