Explain stoke,s law ...​

Answer 1

Stokes Law, named after George Gabriel Stokes, describes the relationship between the frictional force of a sphere moving in a liquid and other quantities (such as particle radius and velocity of the particle). If a sphere or a body moves through a fluid, a friction force must be overcome.

Formula

F=6 \pi r \eta v

F = drag force

\pi = pi

r = sphere radius

\eta = fluid viscosity

v = velocity of the sphere

Answer 2

Answer:

In 1851, George Gabriel Stokes derived an expression, now known as Stokes law, for the frictional force – also called drag force – exerted on spherical objects with very small Reynolds numbers in a viscous fluid
