In Millikan's oil drop experiment, an oil drop of radius 0.02 mm and density 1.2 × 10ʻ kg falls in air. The coefficient of viscosity of air at the temperature of the experiment is 1.8 x 10 Pa-s. (a) Find the terminal velocity of the drop. (b) What is the viscous force on the drop at this velocity? Neglect buoyancy due to air. -3
