Marks: +1, -0

A metallic cubical solid block of side L is slowly lowered continuously in a large vessel, filled with water. Let d be the depth of the lower surface of the block, measured from the surface of the water, at some instant. The graph which represents correctly the variation of the buoyant force F with depth d is:

Validate

Solution:

\Pressure=\text "thrust"/\text "area"=\text "buoyant force (B)"/\text "area (a)"

B = Adgρ (P = ρgd)
Here, A, g & ρ are constant
So B ∝ d
Thus, when it is dipped completely then B becomes constant
