Question

A capillary tube $\left(A\right)$ is dipped in water. Another identical tube $\left(B\right)$ 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.

Answer 1

The correct option is C

Soap solution has lower surface tension as compared to pure water so capillary rise $\left(h\right)$ is less for soap solution.
Therefore option (c) is correct.
