• ### Millikan's oil drop experiment

In 1909 Robert Millikan was the first to find the charge of an electron in his now-famous oil drop experiment. In the experiment, tiny oil drops are sprayed into auniform electric field between a horizontal pair of oppositely charged plates. The drops are observed with a magnifying eyepiece, and the electric field is adjusted sothat the upward force on some negatively charged oil drops is just sufficient to balance the downward force of gravity. That is, when suspended, upward force...
