A) 10/9
B) 3/10
C) 10/3
D) 9/10
Correct Answer: D
Solution :
Height of liquid column rises in a capillary tube is given by, \[h=\frac{2T}{r\rho g}\] \[\therefore \] \[\frac{{{h}_{1}}}{{{h}_{2}}}=\frac{2{{T}_{1}}}{r{{\rho }_{1}}g}\times \frac{r{{\rho }_{2}}g}{2{{T}_{2}}}=\frac{{{T}_{1}}}{{{T}_{2}}}\times \frac{{{\rho }_{2}}}{{{\rho }_{1}}}\] \[=\frac{60}{50}\times \frac{0.6}{0.8}=\frac{36}{40}=\frac{9}{10}\]
