# The fundamental unit which has the same power in the dimensional formula of surface tension and coefficient of viscosity is:

mass

##### SOLUTION
Surface tension $= \dfrac{F}{l} = \dfrac{M^{1}L^{1}T^{-2}}{L^{1}} = M^{1}T^{-2}$
Coeff of viscosity $= \dfrac{k}{qA\dfrac{dv}{dz}} = \dfrac{M^{1}L^{1}T^{-2}}{\dfrac{L^{2}LT^{-1}}{L}} = M^{1}L^{-1}T^{-1}$
Hence, mass has the same power.
