Normal atmospheric pressure, P=1.013× 105Nm- 2 Let h be the height of the wine column. Then, P=hρ g Or h=(P/ρ g)=(1.013 × 105/984 × 9.8)=10.5 m

Q. Torricelli's barometer used mercury. Pascal duplicated it using French wine of density $984 k g m^{- 3}$ . The height of the wine column for normal atmospheric pressure is

$10 .5 m$

$6 .58 m$

$7 .50 m$

$10 .8 m$

Normal atmospheric pressure, $P = 1.013 \times 1 0^{5} N m^{- 2}$
Let h be the height of the wine column. Then,
$P = h ρ g$
Or $h = \frac{P}{ρ g} = \frac{1.013 \times 1 0 ^{5}}{984 \times 9.8} = 10.5 m$
