A water vessel of mass 300kg having volume of 900m³ floats on water, while 2.94 × 10^6 N bouyancy acts on it. The water vessel is tried to use as a completely immersed submarine by keeping it's shape unchanged.
How many portions of volume of the water vessel is immersed, when it floats on water?
Answers
Answer:
Buoyancy and Archimedes’ Principle
The buoyant force on an object can be calculated using the Archimedes principle.
LEARNING OBJECTIVES
Calculate the direction of the buoyancy force
KEY TAKEAWAYS
Key Points
The buoyancy force is caused by the pressure exerted by the fluid in which an object is immersed.
The buoyancy force always points upwards because the pressure of a fluid increases with depth.
You can calculate the buoyancy force either directly by computing the force exerted on each of the object’s surfaces, or indirectly by finding the weight of the displaced fluid.
Key Terms
buoyant force: An upward force exerted by a fluid that opposes the weight of an immersed object.
Archimedes principle: The buoyant force exerted on a body immersed in a fluid is equal to the weight of the fluid the body displaces.
When you rise from soaking in a warm bath, your arms may feel strangely heavy. This effect is due to the loss of the buoyant support of the water. What creates this buoyant force ? Why is it that some things float and others do not? Do objects that sink get any support at all from the fluid? Is your body buoyed by the atmosphere, or are only helium balloons affected?
