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. (a) 1.12
B. (b) 1.1
C. (c) 1.05
D. (d) 1.0

Answer 1

Correct Answer - B
Pressure in limb I at B=Pressure in limb II at A
`hrho_1g=hrho_2g`
`impliesrho_1=rho_2`
