10 m is the correct answer.

C= q/2 = 1.

D = 2 c/ GAMMA.
= 2*1/ 0.002.
= 1000 cm.
= 10 m.

Yes, the answer is 10m.

Yes, correct @Abhijeet.

Depth of tension crack= 2c/Y.
Where c= cohesion.
And from unconfined compression shear test cohesion = q/2 , q=unconfined compressive strenght.
So answer is 10 m.
@Deepak C = cohesion.=q/2.

The answer should be 20m. Not 2m as per unit conversion. Please explain it.

Thanks @Deepak.

Depth of tension crack, d = (2xC)/Y = 2.0 m.

C = Unconfined compressive strength.

Y = Saturated unit weight.

And, maximum unsupported depth of cutting = 2d.
