An object sinks when it displaces a volume of liquid that has a weight

Question

BlackTom AI · Accepted Answer

Reframing the question in my own words helps: when does an object sink in a liquid? The key physical idea is buoyancy, which is the upward force equal to the weight of the displaced liquid (Archimedes’ principle).
Option 1: 'more than the object's weight.' If the weight of the displaced liquid were greater than the object's weight, the buoyant force would exceed the object's weight, causing the object to rise or float up, not sink. This makes this option incorrect for a sinking scenario.
Option 2: 'None of the above.' Since there is a statement that correctly describes sinking, this option cannot be right because it would falsely deny the existence of a true condition for sinking.
Option 3: 'equal to the object's weight.' If the buoyant force exactly matches the object's weight, the forces balance and the object would be neutrally buoyant (neither sink nor rise) in ideal conditions. This does not describe sinking, so this choice is not correct for the given condition.
Option 4: 'less than the object's weight.' When the weight of the displaced liquid (buoyant force) is less than the object's weight, the net force is downward, causing the object to sink. This aligns with the behavior described in the question.
In summary, the sinking condition corresponds to a buoyant force that is smaller than the object's weight, which is captured by the statement in Option 4.
