Determine the radius of the droplet

Reference no: EM13305170

An oil droplet with 13.0 excess electrons is observed between two parallel electrodes spaced 11.0mm apart. The droplet hangs motionless if the upper electrode is 25.0V more positive than the lower electrode. The density of the oil is 860 kg/m^3. What is the radius of the droplet?
