Question

Torricelli's barometer used mercury. Pascal duplicated it using french wine of density $984kg/m^3$. The height of the wine column for normal atmospheric pressure is

• A. $9.5m$
• B. $10m$
• C. $10.5m$
• D. $11m$

Answer 1

Answer: (C)

$10.5m$

$\text{Since Pressure is same}$

${\rho }_{m}g{h}_m={\rho }_{w}g{h}_w$

$13600\times 10\times 0.76=984\times 10\times h_{\omega }$

$h_w=10.5m$
