How did he determine the mass of an oil drop and the charge of the electron?
 
Physics news on Phys.org
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.
