A. pressure per unit length on either side of the imaginary line drawn on the liquid surface at rest B. force per unit length on either side of the imaginary line drawn on the liquid surface at rest C. current per unit length on either side of the imaginary line drawn on the liquid surface at rest D. area per unit length on either side of the imaginary line drawn of the liquid surface at rest
Correct Answer: B
Explanation
Force per unit length. Mathematically, surface tension \(=\frac{F}{L} Nm ^{-1}\)
