WBCS.LIVE practice question

A boat floating in a tank is carrying some passengers. If the passengers drink water from the tank, how will it affect the water level of the tank?

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

Answer options

  1. It will go down.
  2. It will rise.
  3. It will depend on the atmospheric pressure.
  4. It will remain same.

Correct answer and explanation

Correct answer: It will remain same.

Explanation: āœ… Correct Answer: D. It will remain same. šŸ“š Explanation: When the passengers drink water from the tank, the total weight of the boat and the passengers remains the same. According to Archimedes' principle, the boat will continue to displace the same amount of water. Therefore, the 'water level' of the tank will not change at all. This is a classic physics problem that tests the understanding of internal mass changes in a floating system.
