For a floating body, buoyant force acts at the

1. centroid of the floating body
2. center of gravity of the body
3. centroid of the fluid vertically below the body
4. centroid of the displaced fluid

Correct answer: centroid of the displaced fluid

Solution

The buoyant force acts through the center of buoyancy, which is the centroid of the displaced fluid volume. It is not generally the centroid of the body or its center of gravity.
