1 atmospheric pressure is taken as the pressure exerted by a mercury column of height 76 cm . Wh at is the approximate height of an air column that will produce one atmospheric pressure on its bottom ? [Assume that the temperature and density of a ir and th e value ofg remains constant throughout the a ir column .]
`[rho_("mercury")=13.6xx10^3kg//m^3` and `rho_("air")=1.3kg//m^3`]
