A capillary tube (A) is dipped in water. Another identical tube (B) is dipped in a soap-water solution. Which of the following shows the relative nature of the liquid columns in the two tubes?

A

B

C

D

Text Solution

Verified by Experts

The correct Answer is:
C
Surface tension of soap solution is less than that of water.
As `h=(2Scostheta)/(rrhog)` or `h prop S`
Therefore, the height of liquid raised in the capillary tube is less for soap solution and more for pure water . Hence option (c) is correct.
