Questions Related to floatation

The magnitude of buoyant force acting on an object immersed in a liquid depends on
physics floatation pressure in fluids pressure in liquids introduction to pressure
  1. Volume of object immersed in the liquid.

  2. Density of the liquid.

  3. Both A and B

  4. None

Show answer
Correct Option: C
Explanation:

According to Archimedes Principle, the magnitude of buoyant force experienced is equal to the weight of liquid displaced by it by being placed in it.

Hence $B=V _{immersed}\rho g$
Hence $B$ depends both on $V _{immersed}$ and $\rho$.
Correct answer is option C.

The property of a fluid to exert a buoyant force on an object immersed in it is known as _______.

physics floatation pressure in fluids pressure in liquids introduction to pressure

  1. Adhesion

  2. Buoyancy

  3. Cohesion

  4. none of these

Show answer
Correct Option: B
Explanation:

The property of fluid to exert a buoyant force on an object immersed in it known as Buoyancy .

so  option (B) is correct

When a body is partially or completely immersed in a fluid at rest, it experiences an upthrust which is equal to the weight of the fluid displaced by it.

physics floatation pressure in fluids pressure in liquids introduction to pressure

  1. True

  2. False

Show answer
Correct Option: A
Explanation:

The given statement is the statement of archimedes principle , so it is true 

hence option (A) is correct

The upward force exerted by the floating body on the fluid is known as upthrust.

physics floatation pressure in fluids pressure in liquids introduction to pressure

  1. True

  2. False

Show answer
Correct Option: B
Explanation:
Upthrust is the upward force acting on the floating body and is exerted by the fluid .
so given statement is false

hence option (B) is correct
