Q. A stable submerged body has :

A
Centre of gravity below centre of buoyancy
B
Centre of gravity below metacentre
C
Centre of gravity above centre of buoyancy
D
Centre of gravity above metacentre
Solution:
  • A submerged body is in stable equilibrium if the centre of gravity of body lies below the centre of buoyancy.
  • A submerged body is in unstable equilibrium if the centre of gravity of body lies above the centre of buoyancy.
  • A submerged body is in neutral equilibrium if the centre of gravity and the centre of buoyancy coincides.
