If the terminal velocity of the falling drop is known, it is 6.3 mm/s. Then there is equilibrium (drops do not move) after being given a voltage of 1.2 kV. Determine the charge of the oil drop! (Known: oil drop radius 1.9×10 m; air viscosity 1.85x10⁵ Ns/m²; air density 1.184 kg/m³, plate spacing 1 cm, and oil density 920 kg/m³).
