1.8 A ball, when released underwater, will rise towards the surface with velocity v. This velocity depends on the density pb and radius R of the ball, on gravity g, and on the density of and kinematic viscosity v of the water. (a) Find a dimensionally reduced form for v. (b) In fluid mechanics, using Stokes' Law, it is found that V= 28 R² (Pb − Pƒ) 9vpf 1.8 A ball, when released underwater, will rise towards the surface with velocity v.
