Question

state and prove Stokes law​

Answer 1

Answer:

Proof of Stokes' Law: Introduction: The viscous force acting on a spherical body falling in a liquid with velocity v is F = 6πη r v. when a body falls in a liquid, it drags the layers of liquid with it downward while the fluid at large distance from the body remains unaffected

STOKES LAW

• 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. the law that the frequency of luminescence induced by radiation is usually less than the frequency of the radiation.

According to this law F = 6πrηv, where

• r is the radius of the ball
• v is its velocity
• η is the viscosity of the medium.
