Surface Tension:
It is defined as force per unit length in the plane of the liquid surface at right angles to either side of an imaginary line drawn to the surface.
Mathematically,
\(\rm Surface\;Tension = \frac{{Force}}{{Length}}\)
- It is the tendency of the liquid surface to shrink into a minimum surface area.
- The SI Unit of surface tension is N m-1
- It allows insects to float and slide on the water surface, usually more dense than water
- The molecules at the surface have unbalanced force rather than molecules at deeper and the resultant force moves downward this is surface tension.
- Dimensional formula is MT-2
Note:
In this question, the correct option is given in the CGS unit but the question is asked about the SI unit. So The marked option is the most appropriate.
