Stokes' law is used for the measurement of particle size in soil, and it relies on certain simplifying assumptions. These assumptions are: A. Particles must be spherical, smooth, and rigid: This assumption is necessary for the calculation of the drag force acting on the particles. B. Fall must be unhindered: Stokes' law assumes that the particles are freely falling through a liquid medium without any obstructions or interference from other particles. D. Size of particles must be small compared to the size of molecules of the liquid: This assumption ensures that the motion of the particles is primarily influenced by viscous drag forces rather than other forces, such as inertial forces.
