Question

76 cm vertical height of a mercury column, exerts a pressure of 101292.8 Nm$^{–2}$. If "g" = 9.8 ms$^{–2}$. What is density of mercury ?​

Answer 1

Answer:

$\underline{Given:}$

Height of mercury column (h) = 0.76 m.

Acceleration due to gravity (g) = 9.8 ms$^{–2}$

Pressue of mrecury column (P) = 101292.8 Nm$^{–2}$

We know that,

Pressure of mercury column = height of mercury column × density of mercury column × acceleration due to gravity

$\implies$ P = h × d × g

$\implies$ d = P/h.g

$= 13600 \: kgm {}^{ - 3}$

Hence, density of mercury is 13600 kgm$^{–3}$
