Q1:

The effective size of particles of soil is denoted by

A D10

B D20

C D30

D D60

ANS:A - D10

D10 is termed as the effective particle size it means that 10 percent of the particles are finer and 90 percent of the particles are coarser than that particular particle size D10. Because it gives the maximum particle diameter of the smallest 10% of soil particles.
