As we learnt in 

Surface tension, surface energy -

M^{1}L^{0}T^{-2}

-

 

Tensor Quantity -

Which are not completly specifed even by magnitude and direction.

- wherein

i.e. the moment of inertia, co-efficient of viscosity

 

Surface tension [M L0T-2]

Viscosity [M L-1T-1]

Clearly mass has the same power in two physical quantity.


Option 1)

Mass

Option is correct

Option 2)

Length

Option is incorrect

Option 3)

Time

Option is incorrect

Option 4)
