Question

What is stoke's law ?

Answer 1

Answer :

Stoke's Law -

If a spherical body moves in a liquid in rest then the liquid applies a drag force also known as viscous force on the body opposite to the direction of the motion of the body.

The value of this force is -

⇒ $F=6\pi\eta rv$

Here,

$\eta$ is the coefficient of viscosity.

$r$ is the radius of that spherical body.

$v$ is the velocity of the body.

The above formula was given by Stoke therefore it is known as Stoke's la.
