Question

Archimedes principle is used for

• A. Determining the force applied on the object
• B. Determining the relative density of the object
• C. Determining the gravitational constant
• D. All the above

Answer 1

Answer: (B)

Determining the relative density of the object

Archimedes' principle is very useful for calculating the volume of an object that does not have a regular shape. The oddly shaped object can be submerged, and the volume of the fluid displaced is equal to the volume of the object. It can also be used in calculating the density or specific gravity of an object.

$\text{Relative density}=\frac{\text{density of unknown material}}{\text{density of water}}$
