KillGorack / Physics 2010 / Spherical particles of density 2.0 g/cm3 are shaken in a container of water (viscosity = 1.0*10^-3 N·s/m3). The water is 8.0 cm deep and is allowed to stand for 30 minutes. What is the radius of the largest particles still in suspension at that time?

The following physics responses are provided by a student and, as such, should be considered in that context. While every effort is made for accuracy, absolute correctness cannot be fully guaranteed.
