Surface tension - force applied per unit distance, i.e kg/(s*s).

Muhammad Farooq said: (Sep 6, 2013)  
Surface tension- force applied per unit distance so N/m.

Anoop said: (Jan 5, 2014)  
Surface tension - force/length so N/m.

Fakirjasyal said: (Sep 16, 2014)  
I think surface tension is force/area so it should be n/m.

Ravikumar said: (Feb 24, 2015)  
Surface tensions force for unit distance.

Rajat said: (Jun 22, 2015)  
It should be force per unit area.

Malvi said: (Apr 29, 2016)  
Surface tension = force /area.
So, Nm/m2.
=> N/m or J/m2.

Tan said: (Jul 4, 2016)  
N/m is the correct answer.

Mohd Suhel said: (Jul 25, 2016)  
Force per unit lenth, ie = f/l = N/M.

In cgs its unit is = dyne/cm.

Jalsngh Jatav said: (Nov 5, 2016)  
Surface tension is a force applied on the surface to the length of the surface.

Akshay Jadhav said: (Feb 8, 2017)  
Surface tension is a force (N) acting over a surface area (A) having unit width.

So, Area= (1*m). Therefore, answer must be N/m.

In this why the tensions are not measured in kg?

Does kg represent load?

Bhoopender said: (Dec 15, 2017)  
Stress = P/A =N/sqm.

Umesh said: (Jul 26, 2019)  
The SI unit N/m is right.
