In Millikan's oil drop experiment. What is the terminal speed of an uncharged drop of radius 2.0 times 10^-5 m and density 1.2 times 10^3 kg m^-3. Take the viscosity of air at the temperature of the experiment to be 1.8 times 10^-5 Pa s. How much is the viscosity force on the drop at that speed? Neglect buoyancy of the drop due to air.

1.	In Millikan's oil drop experiment. What is the terminal speed of an uncharged drop of radius 2.0 times 10^-5 m and density 1.2 times 10^3 kg m^-3. Take the viscosity of air at the temperature of the experiment to be 1.8 times 10^-5 Pa s. How much is the viscosity force on the drop at that speed? Neglect buoyancy of the drop due to air.
Answer» SOLUTION :`5.8 CM s^-1,3.9 TIMES 10^-10 N`
