Question: The buoyant force on an object submerged in a fluid is equal to: (2022)

Options:

Correct Answer: The weight of the fluid displaced

Exam Year: 2022

Solution:

According to Archimedes\' principle, the buoyant force on a submerged object is equal to the weight of the fluid displaced by the object.

The buoyant force on an object submerged in a fluid is equal to: (2022)

The buoyant force on an object submerged in a fluid is equal to: (2022)

Step 1: Understand what buoyant force is. It is the upward force that a fluid exerts on an object submerged in it.
Step 2: Learn about Archimedes' principle. This principle states that the buoyant force on an object is equal to the weight of the fluid that the object displaces.
Step 3: Visualize the object in the fluid. When the object is submerged, it pushes some of the fluid out of the way.
Step 4: Measure the volume of the fluid that has been displaced by the object. This is the same volume as the part of the object that is underwater.
Step 5: Calculate the weight of the displaced fluid. You can do this by multiplying the volume of the displaced fluid by the density of the fluid and the acceleration due to gravity.
Step 6: Conclude that the buoyant force is equal to this weight of the displaced fluid.

Buoyant Force – The upward force exerted by a fluid on a submerged object, equal to the weight of the fluid displaced.
Archimedes' Principle – A principle stating that the buoyant force on an object is equal to the weight of the fluid it displaces.
