A body is floating in a liquid partly immersed. The body and the liquid are taken to moon. The body
A. will continue to float as before
B. floats with greater part immersed
C. floats with lesser part immersed
D. will sink
Answer: Option A
Solution (By Examveda Team)
When a body floats in a liquid, the condition of equilibrium is given by weight of the body = weight of the liquid displaced.This relationship is based on Archimedes’ principle, which depends on the gravitational acceleration (g).
On taking the body and the liquid to the Moon, the value of g decreases equally for both the body and the displaced liquid.
Since both the weight of the body and the buoyant force depend linearly on g, the ratio between them remains the same.
Therefore, the fraction of the body immersed in the liquid does not change.
The body will continue to float as before, with the same part immersed as it was on Earth.
Hence, the correct answer is: The body will continue to float as before.
