Question

A cubical block is floating in a liquid with half of its volume immersed in the liquid

Answer 1

where Vl is the volume of the liquid displaced and σ is the density of the liquid. so volume of the body in liquid only depends on the densities of the two. It will not be get affected when system moves upward or down word. hence volume in the liquid will remain half.

Answer 2

Explanation:

Fraction of volume immersed in the liquid Vm=(ρσ)V ie., it depends upon the densities of the block and liquid. So there will be no change in it if system moves upward or downward with constant velocity or some acceleration. Know top 5 best Physics books for JEE advanced preparation in 2020.
