Expert Solution
Step 1
Solution
Correct option of the above question given in 2 step with explanation
Step 2
Solution (1) Apparent cohesion does not arise From
(C) Apparent mechanical forces
Explanation- Apparent cohesion is caused due to by
(1) Cohesion is caused by hydrogen bonding and van dar walls forces and adhesion is caused by electrostatic and mechanical forces
(2)Negative capillary pressure (which is lost upon wetting)
(3) Pore Pressure response during Undrained loading (which is lost through time)
Solution (2) In a drained condition test
(b) Pore water pressure is less than hydro-static pressure
Explanation- In drained condition there are permeable and water is allow freely from that so pore water pressure should be less than the hydro static pressure
