Given:
Depth of the stone from the water surface,

h = 500 m

,
Area of the plane surface of the large stone,

A = 2 m^{2}

Density of water,

ρ_{w} = 1 0^{3} kgm^{- 3}

Force

(F)

is given by

F = P \times A = (h ρ_{w} \times g) A \Rightarrow F = (500 \times 1 0^{3} \times 10) \times 2 = 1 0^{7} N / m^{2}

The force does not depend on the orientation of the rock when the surface area of the stone remains the same.
