Surface tension is a word which is linked to the liquid surface. It is a physical property of liquids, in which the molecules are drawn onto every side. This is a type of dragging force per unit length. On the surface of the liquids, there is no other molecules surround each atom. So the surface layer gets attracted inwards.
The formula for finding surface tension is articulated as,
Surface Tension formula
T = F/l
Where,
T= surface tension(N/m)
F = force per unit length (N)
l=length in which force act(m)
