Mechanical analysis of soil makes use of

Answer: Option B

Mechanical analysis is the determination of the size range of particles present in the soil and it is expressed as a percentage of the total dry weight. And its analysis is based on Stroke's law, which states that the terminal velocity of settling of spherical particles in suspension varies with the square of the diameter of the sphere, the density and viscosity of the field and the density of the sphere (soil particles are considered as spheres).
