Solution

The correct option is B h2dg
Let the atmospheric pressure be considered as negligible.

From the surface of water as we move downwards , the pressure will keep on increasing.

Pressure at any depth x will be P=dxg

The force exerted on any area will be kdx where k is the perimeter of the cylinder, dF=PdA=dxgk.(dx)

Avg force across the cylinder will be,
<F>=h0dxgk.(dx)kh
<F>=hdg/2
