A 0.80-?m-diameter oil droplet is observed between two parallel electrodes spaced 11mm apart. The droplet hangs motionless if the upper electrode is 32.0V more positive than the lower electrode. The density of the oil is 885kg/m3.What is the droplet's mass?What is the droplet's charge?Does the droplet have a surplus or a deficit of electrons? How many?
