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.

About Physics of Solids
Solids are compared through crystal structure, amorphous arrangement, elasticity, plastic deformation, stress, strain and Young’s modulus. Electrical behavior depends on available charge carriers and band structure, so conductors, insulators and semiconductors must be distinguished from mechanical properties such as strength, stiffness and brittleness.
