In Millikan's oil-drop experiment, one looks at a small oil drop
held motionless between two plates. Take the voltage between the
plates to be 2006 V, and the plate separation to
be 2.29 cm. The oil drop (of density 0.81
g/cm3) has a diameter
of 4.00 ✕ 10−6 m. Find the
charge on the drop, in terms of electron units.
