คำอธิบาย
Note:The principle of floatation states that a floating body displaces its own weight of the fluid or which its float.
For object to sink weight of the object (W) > upthrust of the fluid (v) i.e. w > u
(i.e. weight of the body (or object) mass of the fluid)
For object to sink weight of the object (W) > upthrust of the fluid (v) i.e. w > u
(i.e. weight of the body (or object) mass of the fluid)
