Question
Explain the Archimedes principle with an example.
✓
Answer
Principle:
A body immersed in a fluid experiences a vertical upward buoyant force equal to the fluid it displaces.
Explanation:
(1) 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.(2) Due to the upthrust, the body loses a part of its weight equal to upthrust.
Upthrust = Weight of the fluid displaced.
= Apparent loss of weight of the body.
Apparent weight of an object = True weight of object in air – upthrust.
