Spherical particles of a given material of density p are released from rest inside a liquid medium of lower density. the viscous drag force may be approximated

Spherical particles of a given material of density p are released from rest inside a liquid medium of lower density. The viscous drag force may be approximated by the Stoke's law, ie, F = 6nnRv, where n is the viscosity of the medium, R the radius ofa particle and vits instantaneous velocity. If t(m) is the time taken by a particke of mass m to reach half its terminal velocity, then the ratio r(8m) / t(m) is a 8 20. h 1/8
