Updated On: Jun 26, 2026
- $Nm^{-1}$
- $Nm^{-2}$
- $Nm^{2}$
- $Nm$
- $N$
Show Solution
Verified By Collegedunia
The Correct Option is A
Solution and Explanation
Step 1: Concept
Surface tension ($T$) is defined as force per unit length.
Step 2: Meaning
$T = \frac{F}{L}$.
Step 3: Analysis
Unit of Force is Newton ($N$) and unit of length is meter ($m$).
Step 4: Conclusion
The SI unit is $N/m$ or $Nm^{-1}$. Final Answer: (A)
