Question

Explain Stoke's law?

Answer 1

The law that the force that retards a sphere moving through a viscous fluid is directly proportional to the velocity of the sphere, the radius of the sphere, and the viscosity of the fluid is called stoke's law.

Answer 2

according to stokes law, the backward viscous force acting on a small spherical body of radius r moving with uniform velocity v through fluid of viscosity n is given by
F=6πnrv (n=eta)
