Dimensional Formula of Surface Tension
The dimensional formula of surface tension is given by,
M1 L0 T-2
- M = Mass
- L = Length
- T = Time
Surface Tension (T) = Force × Length-1 . . . . . (1)
Since, Force = Mass × Acceleration
And, acceleration = velocity × time-1 = [L T-2]
∴ The dimensional formula of force = M1 L1 T-2 . . . . (2)
On substituting equation (2) in equation (1) we get,
Surface Tension (T) = Force × Length-1
Or, T = [M1 L1 T-2] × [L-1] = M1 T-2.
Therefore, surface tension is dimensionally represented as M1 T-2.
