Solution

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

TR=SurfacetensionRadiusofthecapillarytube

=MT-2L

=ML-1T-2= Pressure

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

Thus, option A is the correct answer.
