Oil Spill Facts: Lesson for Kids

In Millikan’S Oil Drop Experiment, What is the Terminal Speed of an Uncharged Drop of Radius 2.0 × 10–5 M and Density 1.2 × 103 Kg M–3? Take the Viscosity of Air at the Temperature of the Experiment to Be 1.8 × 10–5 Pa S. How Much is the Viscous Force on the Drop at that Speed? Neglect Buoyancy of the Drop Due to Air - Physics | Shaalaa.com

In a Millikan oil-drop experiment, the condenser plates are spaced 2.00 cm apart, the potential across the plates is 4000 V, the rise or fall distance is 4.00 mm, the density of the oil droplets is 0.800 g / cm^3, and the viscosity of the air is 1.81 ×10^-5 kg ·m^-1 s^-1 . The average time of fall in the absence of an electric field is 15.9 s The following different rise times in seconds are observed when the field is turned on: 36.0,17.3,24.0 11.4, 7.54. (a) Find the radius and mass of the drop
