Give the dimensional formula of surface tension.

(N/A) Surface tension $(T)$ is defined as the force per unit length acting on the surface of a liquid.
Mathematically,$T = \frac{F}{L}$,where $F$ is the force and $L$ is the length.
The dimensional formula of force $(F)$ is $[M^1 L^1 T^{-2}]$.
The dimensional formula of length $(L)$ is $[L^1]$.
Therefore,the dimensional formula of surface tension is $[T] = \frac{[M^1 L^1 T^{-2}]}{[L^1]} = [M^1 L^0 T^{-2}]$.
