. State Stokes’ Law

Best Answer

Explanation-:

When a solid object moves through a fluid then, its motion is opposed by viscous force. This viscous force exerted by fluid on object depends on

i. Velocity (v) of body

ii. Size of body

iii. Shape of body

iv. Viscosity of fluid

The viscous force (or drag) Fv on a spherical body of radius (r) moving with velocity (v) in a medium of viscosity (n ) is given by

This relation is called Stokes’ law.
