A very small particle of diameter dp and density ρp freely settles at constant velocity in a tank of depth L containing liquid of viscosity μl. The density of the liquid is ρl where ρl < ρp. The velocity of particle in the liquid can be expressed as
A
g(ρp - ρl)dp²/(18 μl)
B
g(ρp - ρl)dp²/(3 μl)
C
g(ρp - ρl)dp/(18 μl)
D
g(ρp - ρl)L/(18 μl)

Correct : c
