B)charge
C)ratio of mass to charge
D)speed

Question

Quizplus · Accepted Answer

Millikan's "oil drop" apparatus was used to determine the charge of the electron, specifically the fundamental unit of electrical charge. By balancing the gravitational force on an oil droplet against the electrical force, Millikan was able to calculate the charge on the droplet and thus determine the charge on a single electron.
