Question

In a u-tube as shown in the fig. water and oil are in the left side and right side of the tube respectively. The heights from the bottom for water and oil columns are 15 cm and 20 cm respectively. The density of the oil is
$[take ρ_{water} = 1000 kg / m^{3}]$

Easy

A

$1333 kg / m^{3}$
B

$1200 kg / m^{3}$
C

$750 kg / m^{3}$
D

$1000 kg / m^{3}$

Solution

In equilibrium
Pressure at A = Pressure at B.
$P_{a} + 0 .15 \times 10^{3} \times g = P_{a} + 0 .20 \times d_{0} g$
$\begin{aligned} d_{0} = \frac{0 .15 \times 10^{3}}{0 .20} \\ = 0 .75 \times 10^{3} \\ = 750 kg / m^{3} \end{aligned}$
