Physics Surface Tension Capillarity Single Correct MCQ

Published on: September 12, 2026

Water rises in a capillary tube to a certain height such that the upward force due to surface tension is balanced by $75 \times 10^{-4} \mathrm{N}$ force due to the weight of the liquid. If the surface tension of water is $6 \times 10^{-2} \mathrm{Nm}^{-1}$ , the inner circumference of the capillary must be

$1.25 \times 10^{-2} \mathrm{m}$

$0.50 \times 10^{-2} \mathrm{m}$

$6.5 \times 10^{-2} \mathrm{m}$

$12.5 \times 10^{-2} \mathrm{m}$

Text Solution

Verified by Experts

The correct answer is:

$6 \times 10^{-2} \times$ Circumference = Force

$\begin{pmatrix} \cdot \\ \cdot \quad \cdot \end{pmatrix}$ Circumference $= \frac{75 \times 10^{-4}}{6 \times 10^{-2}} = 12.5 \times 10^{-2} \mathrm{m}$
