A body floats in a liquid contained in a beaker. The whole system, as shown, falls freely under gravity. The upthrust on the body due to the liquid is:
Correct answer: A. Zero
- A. Zero
- B. Equal to the weight of the liquid displaced
- C. Equal to the weight of the body in air
- D. Equal to the weight of the immersed position of the body
Explanation
This is the correct answer according to Archimedes' principle. The upthrust on a body submerged in a liquid is equal to the weight of the liquid displaced by the body. This is a fundamental principle in fluid mechanics.
