What determines whether an object floats or sinks when it placed in a fluid
Homework Answers
This phenomenon was described by Archimedes using the concept of buoyancy. If the density of the object is less than the fluid then it will flow on the fluid otherwise it will sink. Buoyancy is simply the force i.e exerted by the fluid on the object.The weight of the water displaced by an object must be more than the weight of the object.

An object of mass M floats with 1/2 its volume submerged in a fluid (fluid A) of unknown density. An identical object of mass M is then placed in a 2nd unknown fluid (fluid B) where it floats with 2/3 of the objects volume submerged. what is the ratio of densities of the fluid A to fluid B?

Can you use Archimedes' principle to find the density of an object that floats? a. Yes, attach a weight to the object and find the difference in buoyant forces. b. No, the object must be able to sink. c. Yes, a floating object will still displace fluid equivalent to the buoyant force.
