Properties Of Solids And Liquids Question 181

Question: Two capillary tubes of same diameter are put vertically one each in two liquids whose relative densities are 0.8 and 0.6 and surface tensions are 60 and 50 dyne/cm respectively Ratio of heights of liquids in the two tubes $\frac{h_{1}}{h_{2}}$ is [MP PMT 2002]

Options:

A) $\frac{10}{9}$

B) $\frac{3}{10}$

C) $\frac{10}{3}$

D) $\frac{9}{10}$

Show Answer

Answer:

Correct Answer: D

Solution:

Ascent formula $h = \frac{2 T \cos θ}{r d g}$

$\Rightarrow \frac{h_{1}}{h_{2}} = \frac{T_{1}}{T_{2}} \times \frac{d_{2}}{d_{1}}$ ( $r, θ$ and g are constants) $\Rightarrow \frac{h_{1}}{h_{2}} = \frac{60}{50} \times \frac{0.6}{0.8} = \frac{9}{10}$
