Question

If T denotes the surface tension and R, the radius of a capillary tube, then the dimensions of T/R are the same as that of

• A. pressure
• B. energy
• C. force
• D. None of these

Answer 1

The correct option is A

pressure

Explanation for the correct answer:

Option A: Pressure

1. Surface tension = $T$
2. The radius of the capillary tube = $R$

$\frac{T}{R}=\frac{Surfacetension}{Radiusofthecapillarytube}$

$=\frac{M{T}^{-2}}{L}$

$=M{L}^{-1}{T}^{-2}$= Pressure

If T denotes the surface tension and R, the radius of a capillary tube, then the dimensions of $\frac{T}{R}$ are the same as that of pressure.

Thus, option A is the correct answer.
