The SI Unit of Surface Tension is

  1. dyne/cm
  2. N/m
  3. N/m2
  4. m2

Answer: B. N/m

The SI unit of surface tension is N/m.

Solution

Surface tension is the tension of the surface film of a liquid caused by the attraction of the particles in the surface layer by the bulk of the liquid, which tends to minimize surface area”.

T= F/ L

Where; F=force

L=length

T=surface tension

SI Unit =  N/m

CGS Unit = dyne/cm 

Hence Option B is correct. The SI unit of surface tension os N/m.
