Physics
A homogenous block floats on water (a) partly immersed (b) completely immersed. In each case state the position of centre of buoyancy B with respect to the centre of gravity G of the block.
Answer
(a) When a homogenous block floats on water with it's body partly immersed then centre of buoyancy B will lie vertically below centre of gravity, G.
(b) When a homogenous block floats on water with it's body completely immersed then centre of buoyancy B will coincide with centre of gravity, G.
