Question

a) If an object floats, partially submerged, what is true about the buoyancy force and gravitational forces acting on the object?

b) How does the buoyancy force acting on the partially submerged object compare to what the buoyancy force would be if the entire object were submerged?

c) How are the densities of the object and the fluid related if the object floats?

d) Sinks?

e) Remains suspended, neither floating nor sinking?

Answer 1

a) the buoyancy force and the gravitational force will be equal and opposite in nature when the object floats or partially submerged

b)the buoyant force is directly proportional to the submerged volume of the object. Therefore, buoyant force on partially submeregd object will be less than fully submerged object

c)If the object floats, the density of object is less than the liquid it floats in

d)if the object sinks, then the object's density is higher than that of liquid

e)if the object remains suspended, then density of fluid and object are equal
