A wooden block is floating in a liquid in partially submerged condition. If the same set-up is taken at Mount Everest peak, then one should observe that the piece of wood will float with

A)  larger portion above water than previous.

B)  It will sink.

C)  Smaller portion above water than previous.

D)  Remains unchanged

Correct Answer: D

Solution :

In floating condition, Buoyancy force = Weight of block \[V'\rho g=V\sigma g\] \[\Rightarrow \,\,\,\,\,V'=V\left( \frac{\sigma }{\rho } \right)\] It is independent on outside pressure.
