Correct Answer - Option 1 : stable equilibrium
Concept
For submerged body:
Stable Equilibrium: Centre of gravity is below than the centre of buoyancy
Unstable Equilibrium: Centre of gravity is above than the centre of buoyancy
Neutral Equilibrium: Centre of gravity coincides with the centre of buoyancy
One should know what stable and unstable equilibrium is
Let us suppose that a body is given a small angular displacement and then released. Then the body will be said to be in
Stable Equilibrium:
If the body returns to its original position by retaining the originally vertical axis as vertical.
Unstable Equilibrium:
If the body does not return to its original position but moves further from it.
