Hi this the answer of me.
when a body falls through a highly viscous liquid, it drags the layer of the liquid immediately in contact with it. This results in a relative motion between the different layers of the liquid. As a results of this, the falling body experience a viscous force F. Stock performed many experiments on the motion of small spherical bodies in different fluids and concluded that viscous force F acting on the spherical body depends on
1) coefficient of viscosity n of the liquid.
2) Radius a of the sphere and
3) Velocity v of the spherical body.
dimensionally it can be proved that
F= k nav
Experimentally stocks found that
k= 6 pi
F=6pi nav
This is stocks law.
