1. Stable equilibrium. If a body floating in a liquid returns back to its original position, when given a small angular displacement, then the body is said to be in stable equilibrium.

2. Unstable equilibrium. If a body floating in a liquid does not return back to its original position and heels farther away when given a small angular displacement, then the body is said to be in unstable equilibrium.

3. Neutral equilibrium. If a body floating in a liquid occupies a new position and remains at rest in this new position, when given a small angular displacement, then the body is said to be in neutral equilibrium.

It's called unstable equilibrium.

Its answer is neutral equilibrium.

The body is in "Unstable equilibrium".

Because it is Neutral.

No. Because it is unstable.

It is Unstable.

The Answer is neutral. In the neutral position, the body doesn't change the position when centre of buoyancy and centre of gravity consider.

Unstable flow is correct.

Neutral is correct.
