The dimensional formula of surface tension is [L0M1T-2]. Explanation: Surface Tension (T) = Force $\times$ Length−1 ...(1) Since Force = Mass $\times$ Acceleration And acceleration = velocity $\times$ time−1 = [L T−2] $\therefore$ The dimensional formula of force = M1 L1 T−2 On substituting equation (2) in equation (1), we get, Surface Tension (T) = Force $\times$ Length−1 Or, T = [M1 L1 T−2] $\times$ [L−1] = M1 T−2. Therefore, surface tension is dimensionally represented as [L0M1T−2].
