Two identical concrete piles having the plan dimensions 50cm × 50cm are driven into a homogeneous sandy layer as shown in the figures. Consider the bearing capacity factor Nq for ϕ = 30° as 24.

If QP₁ and QP₂ represent the ultimate point bearing resistances of the piles under dry and submerged conditions, respectively, which one of the following statements is correct?

QP₁ > QP₂ by about 100%
QP₁ < QP₂ by about 100%
QP₁ > QP₂ by about 5%
QP₁ < QP₂ by about 5%
