A body fully immersed in a fluid experiences an upward buoyant force equal to
A. Density of the body
B. Weight of the body
C. Weight of the fluid displaced
D. Volume of the body
Answer: Option C
Solution (By JKExamLibrary)
Archimedes' principle: buoyant force = weight of fluid displaced. This force acts upward. If buoyant force ≥ weight, object floats. Submarines use ballast tanks to change weight, altering buoyancy.
Explanation:
R = ρL/A, depends on length (L), cross-sectional area (A), and resistivity (ρ) which depends on material and temperature. Not on colour or transparency.
