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

Answer

1.1

Explanation

From

it is clear that the height of liquid colun I in limb A is (2+h)cm and the height of liquid coluum Ii in limbs B is 2.0 cm and of liquid of column I si h cm. `:. 2xxrho_2 xx g + hxx1.1xxg =(2+h)1.1 xxg`
`or 2rho_2 g = 2xx1.1xxg or rho_2 = 1.1` Thus, the specific gravity of liquid second is 1.1
