A negatively charged oil droplet is placed between the plates of a horizontal parallel plate capacitor. The electrostatic field strength is selected so that the droplet is at rest. Determine the charge of the droplet if the potential difference between the capacitor plates is U = 500 V, the distance between the plates is d = 0.50 cm, the radius of the droplet is r = 7.6 • 10-5 cm, the oil density is p = 0.90 • 103 kg/m3 .
