Compute all parts of given question:
Question: We are centrifuging a collection of particles with diameter 150 nm and average density of 1.10 g/cm3 through a water solution with density 1.0 c/cm3 at 20,000 rpm. The viscosity of the water is 1 x 10-3 Pa s, Pa=1 N/m2
Part A: At a distance of 8.5 cm from the axis of rotation, what is the net force on a particle?
Part B: From Stoke's equation, calculate the frictional coefficient.
Part C: What is the particle's terminal velocity?
Part D: What direction is the net force? What causes this net force?
Explain how you came up the prefixes and answer please.
