On a vertical plane surface submerged in liquid, the distance (d) of the centre of pressure from free surface of liquid is given by which formula among the following options?
(Given: d = Distance of the centre of pressure from free surface of liquid
IG = Moment of Inertia of area about an axis passing through the C.G of the area and parallel to the free surface of liquid
A = Total area of the surface
h = Distance of C.G of the area from the free surface of liquid
ρ = Density of liquid )
1
\(d =\frac{I_G}{Ah}+ \rho\)
2
\(d =\frac{I_G}{Ah}+ h\)
3
\(d =\frac{I_G}{A}+ h\)
4
\(d =\frac{AI_G}{h}+ h\)
