Question

Illustrate with the help of a labelled diagram of a simple barometer that the atmospheric pressure at a place is 76 cm of Hg.

Answer

The vertical height of the mercury column from the mercury surface in the trough to the level in tube is a measure of the atmospheric pressure and the barometric height at normal temperature and pressure at sea level is 0.76 m ( or 76 cm or 760 mm) of mercury.
