A.
The center of buoyancy is located at the center of gravity of the displaced liquid |
|
B.
For stability of a submerged body, the center of gravity of body must lie directly below the center of buoyancy |
|
C.
For stability of floating cylinders or spheres, the e.g. of body must lie below the center of buoyancy |
|
D.
All floating bodies are stable |
