Vedclass · Answer

(C) Surface tension $(T)$ is defined as the force $(F)$ per unit length $(l)$.Mathematically,$T = \frac{F}{l}$.The dimensional formula for force $(F)$ is $[MLT^{-2}]$.The dimensional formula for length $(l)$ is $[L]$.Therefore,the dimensions of surface tension are $T = \frac{[MLT^{-2}]}{[L]} = [ML^0T^{-2}]$.
