In the early 1900s, Robert Millikan used small charged droplets of oil, suspended in an electric field, to make the first quantitative measurements of the electron’s charge. A 0.79-μm-diameter droplet of oil, having a charge of +e, is suspended in midair between two horizontal plates of a parallel-plate capacitor. The upward electric force on the droplet is exactly balanced by the downward force of gravity. The oil has a density of 860 kg/m3, and the capacitor plates are 6.0 mm...

In Millikan's experience, a microscopic oil droplet, with 2 mm radius, is introduced between the plates of a plan capacitor, whose spacing is 5 cm. The oil density is 0.78 g/cm3. With the plates initially discharged, the droplet is observed to fall reaching, due to air resistance, a constant terminal speed v. When applying across the plates a potential difference of 40 kV with the electric field oriented upward, the falling speed doubles. What is the sign and the total...
