There are two things one is pressure intensity and the other is total pressure. Intensity is proportional to the depth of soil and the total pressure is proportional to the square depth of soil.

I think the option B is also the correct one.
Lateral Earth pressure p = k * w * z.
Lateral Earth pressure p = k * w * z.

But ranking theory not considered friction.
Only Coulomb theory considered friction.
So how can say that [D] answer right?

The lateral earth pressure act at h/3 from toe of the wall, and which is p = 0.5*kh^2* unit weight. So answer is C.

Because the earth pressure coefficient is n also equal to 1-sin^2%/1+sin^2&.

p = kwh. So p is proportional to h directly. And k, that's (1-sinφ)/(1+sinφ).
How on the earth proportional to internal friction φ?

I think B and D are right because p = k*w*h, so p is proportional to depth and co-efficient of lateral earth pressure in this k = 1-sin (pi).
So k depends on internal friction then pis also directly proportional to internal friction.
So k depends on internal friction then pis also directly proportional to internal friction.

Answer B is right because lateral pressure of the earth varies with the height of the soil.

As we know,
P = 0.5 kwh^2.
From above P is directly proportional to square of height. So I think option C is right.
P = 0.5 kwh^2.
From above P is directly proportional to square of height. So I think option C is right.
