7.

In S.I. system, the symbol for density is

 [A]. N/m3 [B]. kg/m3 [C]. m3/s [D]. kg

Explanation:

No answer description available for this question.

 Sowmya said: (Jun 11, 2015) 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.

 Mukesh K Patel said: (Oct 2, 2019) Density, Mass density = kg/m3. Weight density = N/m3. So, Ans is also A and B?
