Floating body stability: response to a small angular displacement A floating body is given a small angular displacement and returns to its original position. Identify the equilibrium classification. Choose the correct option.

Concept/ApproachA floating body is in stable equilibrium if, after a small angular displacement, a righting moment acts to restore it to the initial position. This typically requires the metacentre to lie above the centre of gravity (GM > 0).

Final Answerstable equilibrium
