Question

In the given figure, ${\rho }_1,{\rho }_2$ density of liquid in container (1) & (2), and ${\rho }_3$ density of liquid (2) of manometer The level of fluid in both the container is same. Which is the correct condition?

• A. ${\rho }_2>{\rho }_1$
• B. ${\rho }_2<{\rho }_1$
• C. ${\rho }_2={\rho }_1$
• D. cant say

Answer 1

Answer: (B)

${\rho }_2<{\rho }_1$

From the height of the liquid in the manometer we see that the pressure exerted by the liquid in the container 1 is greater than that exerted by the liquid in container 2. Thus the density of the liquid in 1 is greater than the density in container 2.
