Describe Millikan's Oil Drop Experiment!

  1. Nov 23, 2011 #1
    How did he determine the mass of an oil drop and the charge of the electron?

    As regards the mass of the drop i think that he used

    mass = volume x density

    and assumed a spherical shape, knowing the density of the oil, and eliminating the radius r of the drop by doing more than one experiment.
