$2\mathrm{.}1$ A solid particle of density $2500k\frac{g}{m^3}$ falls freely under gravity in water at $20C$ at its terminal velocity.

a$.$ If the particle is spherical with a mass of $1\mathrm{.}0mg,$ what is its terminal velocity?

b$.$ The particle is a cylindrical pellet with diameter $=300m$ and aspect ratio $=3.$ Calculate its terminal velocity.

c$.$ The particle is cubic in shape and is settling at its terminal velocity of $10m\frac{m}{s}.$ calculate the dimension of its side.

d$.$ The particle has a mass of $530g$ and a terminal velocity of $0\mathrm{.}1\frac{m}{s}.$ Determine the sphericity of the particle.
