Unstable equilibrium of a floating body implies
- A. Metacentre M is above centre of gravity G
- B. Metacentre M is below centre of gravity G
- C. Metacentre M coincides with centre of gravity G
- D. None of these
Answer: B. Metacentre M is below centre of gravity G
Explanation: For a floating body, the stability states are governed by the relative positions of the Metacentre (M) and the center of gravity (G). Stable equilibrium occurs when M is above G. Unstable equilibrium occurs when M is below G, creating an overturning moment. Neutral equilibrium occurs when M coincides with G.
