When a small sphere moves at low speed through a fluid, the viscous force opposing the motion is found experimentally to depend on the radius 'r', the velocity 'v' of the sphere, and the viscosity 'η' of the fluid. Find the force 'F' (Stokes's law).

Step 1
We know that the viscous force F depends on the radius r, the velocity v, and the viscosity η of the fluid. So, we can write F = k * f(r, v, η), where k is a constant and f is a function of r, v, and η. Show more…

When an object moves through a fluid, the fluid exerts a viscous force $\overrightarrow{\mathbf{F}}$ on the object that tends to slow it down. For a small sphere of radius $R$ moving slowly with a speed $v$ , the magnitude of the viscous force is given by Stokes' law, $F=6 \pi \eta R v,$ where $\eta$ is the viscosity of the fluid. (a) What is the viscous force on a sphere of radius $R=5.0 \times 10^{-4} \mathrm{m}$ that is falling through water $\left(\eta=1.00 \times 10^{-3} \mathrm{Pa} \cdot \mathrm{s}\right)$ when the sphere has a speed of 3.0 $\mathrm{m} / \mathrm{s} ? \quad$ (b) The speed of the falling sphere increases until the viscous force balances the weight of the sphere. Thereafter, no net force acts on the sphere, and it falls with a constant speed called the "terminal speed If the sphere has a mass of $1.0 \times 10^{-5} \mathrm{kg}$ , what is its terminal speed?
A sphere of radius R moves with velocity u in an incompressible, non-viscous ideal fluid. Calculate the pressure distribution over the surface of the sphere. Do you think that a force is necessary to keep the sphere in uniform motion?
