Question:
A 0.80-μm-diameter oil droplet is observed between two parallel electrodes spaced 11 mm apart. The droplet hangs motionless if the upper electrode is 20 V more positive than the lower electrode. The density of the oil is 885 kg/m3.
a. What is the droplet’s mass?
b. What is the droplet’s charge?
c. Does the droplet have a surplus or a deficit of electrons? How many?

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.
