Question

An object has a density of 0.79 g/cm3. When floating in water, what fraction of the object will be above the surface of the water?

Answer 1

If the buoyant force is greater than the object's weight, the object will rise to the surface and float. If the buoyant force is less than the object's weight, the object will sink. If the buoyant force equals the object's weight, the object will remain suspended at that depth.

Answer 2

Here you go...!!

Density of Object Given 0.79

And of water we know 1g/cm^3
