Which of the below options represents the equation to compute the vertical stress under a uniformly distributed circular load?

\(σ= \left[1-\frac{z^3}{(a^2+z^2 )^{3⁄2}}\right]\)

\(σ=p \left[1+\frac{z^3}{(a^2+z^2 )^{3⁄2}}\right]\)

\(σ=p \left[1-\frac{z^3}{(a^2+z^2 )^{1⁄2}}\right]\)

\(σ=p \left[1-\frac{z^3}{(a^2+z^2 )^{3⁄2}}\right]\)

\(σ= \left[1-\frac{z^3}{(a^2+z^2 )^{3⁄2}}\right]\)
