Question

A U-tube of uniform cross-section (see fig) is partially filled with a liquid $L$. Another liquid $L_1$ which does not mix with liquid $L$ is poured into one side. It is found that the liquid levels of two sides of the tube are the same. While level of liquid $L$ has risen by $2cm$. If the specific gravity of liquid $L$ is $1.1$, the specific gravity of liquid $L_1$ must be ___________.

• A. $1.1$
• B. $1.3$
• C. $1.001$
• D. $1.0$

Answer 1

The correct option is A $1.1$

lectus controler the specific gravity of liquid (ii) is $l_2$ and for liquid -(i) is

$\ell$
