|Why in S.I system density is Kg/m3?
And why not in S.I system surface tension is Kg/m but N/m?
|Yashodha said: (Aug 11, 2015)|
|Density = Mass/volume.
ρ = m/v.
S.I unit is kg/m3.
|Maruthi said: (Jun 29, 2016)|
|Density = mass/volume.
Mass in kg and volume in m^3 so,
density obtained in kg/m^3.
|Suraj said: (Nov 26, 2016)|
|In S. I system force and pressure written as N.
So, unit for surface tension is N/m and unit for density is kg/m3.
|Vinayak Powar said: (Dec 19, 2017)|
|I think it should be N/m3.|
|Jayprakash said: (Jan 4, 2018)|
|Mass density - kg/m3.
Weight density - N/m3.
|Maddy said: (Feb 8, 2019)|
|Density = mass/volume (kg/m^3).
Surface Tension = force/unit length(N/m).
Force (=N) = m (=kg) * a (=m/s^2).
Therefore, ρ = m/v.
S.I unit is kg/m^3.

Mass density = kg/m3.
Weight density = N/m3.
So, Ans is also A and B?
