WBCS.LIVE practice question

Whether an object will float or sink in a liquid, depends on:

Solve this multiple-choice question and check the correct answer with its explanation below.

Answer options

  1. mass of the object only
  2. mass of the object and density of liquid only
  3. difference in the densities of the object and liquid
  4. mass and shape of the object only

Correct answer and explanation

Correct answer: difference in the densities of the object and liquid

Explanation: āœ… Correct Answer: C) difference in the densities of the object and liquid šŸ“š Explanation: According to Archimedes' principle and the laws of floatation, whether an object will sink or float depends entirely on the difference between the density of the object and the density of the liquid. If the object's density is higher than that of the liquid, it sinks; if lower, it floats. The total mass or volume alone does not determine this outcome, as a heavy steel ship floats due to its low overall average density. This fundamental concept is central to fluid mechanics.
