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) Partly immersed - centre of buoyancy B will lie vertically below centre of gravity, G.
(b) Completely immersed - centre of buoyancy B will coincide with centre of gravity, G.

"hello everyone welcome to leader
learning
i'm good pray pure science tutor today's
question is
a homogeneous block floats on water
a partly immersed and the b
completely immersed in each case
state the position of center of bind
seed b
with respect to the center of gravity
g of the block so here
you have to specify the position of
center of buoyancy
with respect to the center of gravity g
of the block so if we talk about
the position that is partly immersed
the block is partly immersed
then the center of gravity
the center of buyoncy
the center of buoyancy b
will lie
vertically
below the center of gravity
but in case of
b situation when it is completely
immersed
in the completely immersed situation
then
center of buoyancy
which is represented by b will
coincide
with the center of gravity
