Question

A body dipped into a liquid experiences an upthrust. State two factors on which upthrust on the body depends.

ICSE Class 9 Physics Chapter Upthrust in Fluids,Archimedes Principle and Floataion

Answer 1

when an object is immersed  in a liquid, it experiences an upward force. This upward force is called as Buoyant Force or Upthrust.
It is due to this upward force, the weight of object appears to be less in liquid than its actual weight.
Factors affecting the Upthrust are:
1. Volume of object immersed in liquid --- as volume increases the upward force increases.
2. Density of liquid:
As the density of liquid increases the upward force exerted also increases.

Answer 2

Two factors of upthrust force:

* Volume of object immersed in liquid

* Density of liquid
