`A` vertical uniform `U` tube open at both ends contains mercury. Water is poured in one limb until the level of mercury is depressed `2cm` in that limb. What is the length of water column when this happens.

Text Solution

Verified by Experts

The correct Answer is:
54.4cm

`lxxrhoxxg=4xx13.6xxrho_(w)xxg implies l=54.4cm`
