Question

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

A. `1.12`
B. `1.1`
C. `1.05`
D. `1.0`

Answer 1

Correct Answer - B
The level of liquid is same in both the limbs. Pressure in limbs l at `B=`Pressure of limb II at `A`.

`hrho_(1)g=hrho_(2)g`
`implies rho_(1)=rho_(2)`
