When a solid sphere moves through a liquid, the liquid opposes the motion with a
force F. The magnitude of F depends on the coefficient of viscosity n of the liquid, the
radius r of the sphere and the speed of the sphere. Assuming that F is proportional to
different powers of these quantities, derive a formula for F using dimension analysis.
