Question

Archimedes' Principle states that when a body is totally or partially immersed in a fluid, the upthrust is equal to :

• A. the weight Of the fluid displaced by it
• B. the weight of the body
• C. volume of the fluid displaced
• D. volume of the body

Answer 1

The correct option is A

the weight Of the fluid displaced by it

Explanation for correct option(s):

Option (A) :

1. .According to Archimedes' principle, when a body is immersed wholly or partially in liquid then an upward force called buoyant force acts on the body which is equal to the weight of the liquid displaced.
2. This upward force is also called Upthrust.
3. Due to the buoyant force, a body submerged partially or fully in a fluid appears to lose its weight, i.e. appears to be lighter.

Hence, Option(A) is correct
