What would be the height of column in barometer if water `("density" = 1000 Kg//m^(3))` is used instead of mercury for measuring atmospheric pressure? 

Text Solution

AI Generated Solution

To find the height of the column in a barometer if water is used instead of mercury for measuring atmospheric pressure, we can follow these steps: ### Step-by-Step Solution: 1. **Understand the Concept**: The atmospheric pressure is the same whether we use mercury or water. The pressure exerted by a liquid column is given by the formula: \[ P = \rho g h \] ...
