Question

Assertion (A): At depth z below the surface of a submerged soil, water pressure is $Y_{w}Z$ and it is the stress caused by the water which is called the "neutral stress".
Reason (R): The water pressure acts equally in all directions and transmits the same fully in grain to grain contact causing compression in the soil.

• A. both A and R are true and R is the correct explanation of A
• B. both A and R are true but R is not a correct explanation of A
• C. A is true but R is false
• D. A is false but R is true

Answer 1

The correct option is C A is true but R is false

(c)
The pore pressure prevents the compression of the soil mass. Pore water pressure is known as neutral pressure because it cannot resist shear stress.
