Force per unit length,$N m^{-1}$

Vedclass · Answer

(B) Definition: Surface tension is defined as the force acting per unit length perpendicular to the line drawn on the surface of the liquid.Mathematical expression: $\gamma = \frac{F}{l}$Dimensions: The force $F$ has dimensions $[MLT^{-2}]$ and length $l$ has dimensions $[L]$. Thus,surface tension has dimensions $[MLT^{-2}] / [L] = [MT^{-2}]$.$SI$ unit: Since force is measured in $N$ and length in $m$,the $SI$ unit is $N m^{-1}$ (or $kg \ s^{-2}$).

Define surface tension and provide its dimensions and $SI$ unit.
