[#309] The depth of centre of pressure (h) for a vertically immersed surface from the liquid surface is given by (where $${I_{ ext{G}}}$$ = Moment of inertia of the immersed surface about horizontal axis through its centre of gravity, A = Area of immersed surface and x = Depth of centre of gravity of the immersed surface from the liquid surface)
Correct Answer
(D) $$frac{{{I_{ ext{G}}}}}{{{ ext{A}}overline { ext{x}} }} + overline { ext{x}} $$
