Strong Inequality Hydrodynamics: Flat Cylinder in Water

[zaevin]

Homework Statement

So, there's a flat cylinder with radius R and Height H fully submerged in water rn. it's denser than water and its distance from its base to the bottom of the tank is h. I gotta calculate the time taken to sink to the bottom, and gotta ignore viscosity so no drag force or turbulence. BUT, what's bugging me is this inequality-

Relevant Equations

10rho_cylinder h<< rho_water R
