Question

For the stability of a floating body, under the influence of gravity alone, which of the following is TRUE?

• A. Metacenter should be below centre of gravity
• B. Metacenter should be above centre of gravity
• C. Metacenter and centre of gravity must lie on the same horizontal line
• D. Metacenter and centre of gravity must lie on the same vertical line

Answer 1

The correct option is B Metacenter should be above centre of gravity


Points To Remember

• The distance between the centre of gravity and metacentre i.e. GM is known as metacentric height.
• If GM = 0, neutral equilibrium
• If GM > 0, stable equilibrium
• If GM < 0, unstable equilibrium
