Explanation / Answer

This was an experiment where an oil droplet was real eased within two electrons in order to show the charge of a droplet. After many experiments they got the value ob a very small integer 1.602176487(40)×1019 C. Nonetheless in absence of an electric field, the velocity of the droplet was measured, the drag force is equal to the gravitational force.

B. in the absence of an electric field, the oil droplet falls freely due to the gravitational force.
