For a floating body how is its weight and buoyant force related?

Question

How is the weight and buoyant force related for a floating body?
My answer

For any floating body the upthrust experienced by the body is equal to the weight of the body and the upthrust or the buoyant force is equal to the weight of the liquid displaced by the immersed part of the body.

Is it correct or it is wrong?

Answer 1

It is correct.  However, instead of the term "upthrust", you should just call it upward force.  Use of the term "thrust" implies the presence of a propulsive force.

Answer 2

I believe that we have Archimedes to thank for this Physics fact.  Suggestion: google Archimedes
