Stability of Floating BodiesHardQuestion 30913

Question

A body is in stable floating equilibrium when:
  1. A
    Centre of buoyancy is above centre of gravity
  2. B
    Metacentre is above centre of gravity
    Correct
  3. C
    Centre of gravity is above centre of buoyancy
  4. D
    Both centres coincide

Correct answer

Metacentre is above centre of gravity

Explanation

Stable equilibrium requires metacentre (M) above centre of gravity (G). If GM > 0, a tilted body rights itself.
