Question

Surface tension has dimensions of

Answer 1

Evaluate the dimension

1. Surface tension is defined as the property of the surface of the fluid that allows it to resist an external force, due to the cohesive nature of the molecules of the liquid.
2. Its formula is, Surface tension$=\frac{\mathrm{Force}}{\mathrm{Length}}$
3. The Dimension of force is $M^1{L}^1{T}^{-2}$
4. The dimension of length is $L^1$
5. So the dimension of Surface tension is $M^1{L}^0{T}^{-2}$

Hence, the dimension of surface tension is $M^1{L}^0{T}^{-2}$
