An oil droplet with 15 excess electrons is observed between two parallel electrodes spaced 12 mm apart.
Question:
An oil droplet with 15 excess electrons is observed between two parallel electrodes spaced 12 mm apart. The droplet hangs motionless if the upper electrode is 25 V more positive than the lower electrode. The density of the oil is 860 kg/m3. What is the radius of the droplet?

Density is a measurement that compares the amount of matter an object has to its volume. An object with much matter in a certain volume has a high density. Density helps us predict whether something will float. In this video, the density of oil is assessed by adding food color to the oil above water.
