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

  • Option 1)

  • Option 2)

  • Option 3)

  • Option 4)

 

Answers (1)

The meniscus of the capillary tube should be concave from outside. Since surface tension of soap solution is small hence the rise in capillary tube is less for soap solution than water

h=\frac{2s\ cos\theta}{\rho\ rg}

h_{soap}<h_{water}

Correct option is 4.


Option 1)

This is an incorrect option.

Option 2)

Option 3)
