Question

The SI unit of surface tension is …………….. 

(A) Pascal 

(B) N s m^-2

(C) km^-2 s 

(D) N m^-1

Answer 1

Correct option is : (D) N m^-1

The SI unit of surface tension is \(Nm^{-1}\)

Answer 2

Correct option is (D) N m^-1

Answer 3

surface tension =force acting perpendicular to the surface/  unit length

                              =f/l

                              =n/m 

so the correct option is d
