Question

For a submerged object, the buoyant force acts at the

a. center of gravity
b. center of mass
c. radius of rotation
d. center of volume
e. all of the above

Answer 1

The buoyant force on a submerged object acts at the object's center of volume, in accordance with Archimedes' principle.

Step-by-step explanation:

For a submerged object, the buoyant force acts at the center of volume. When an object is submerged in a fluid, it experiences a buoyant force (FB) that is equal to the weight of the fluid displaced by the object, a concept known as Archimedes' principle. Whether an object floats, sinks, or remains suspended in the fluid depends on the relationship between the buoyant force and the object's weight. If FB is greater than the object's weight, the object will rise to the surface and float; if FB is less than the weight, the object will sink; if equal, the object can remain at its current depth. This upward force is a result of pressure increasing with depth in the fluid, creating a larger upward force on the object's bottom than the downward force on its top.
