We recently did a lab where we were given an animation of the oil drop experiment, and we were supposed to find the velocity of the droplet when Fg and FQ were in the same direction (v1) and when Fg and FQ were in opposite directions (v2)... Then we found (v1 - v2) and were told to analyze and prove the existence of a smallest unit of electric charge...(adsbygoogle = window.adsbygoogle || []).push({});

Here is the work I've done so far...

v1 (is directly proportional to) Fg + FQ

v2 (is directly proportional to) Fg - FQ

Therefore,

(v1 - v2) (is directly proportional to) (Fg + FQ) - (Fg - FQ)

(v1 - v2) (is directly proportional to) Fg -Fg + 2FQ

(v1 - v2) (is directly proportional to) 2FQ

Am I completely off track, can the fact that (v1-v2) is directly proportional to 2FQ be used to prove the existence of the smallest unit of electric charge?
