Which of the following has the dimension if \(\left[\mathrm{ML}^{2} \mathrm{T}^{-2}\right] ?\)
- A Coefficient of viscosity
- B Surface tension
- C Vapour pressure
- D Kinetic energy
Answer & Solution
Correct Answer
(B) Surface tension
Step-by-step Solution
Detailed explanation
\(\because\) Surface tension \((T)=\) Work done per unit area \[ \begin{aligned} \therefore \quad T &=\frac{d W}{d A} \\ &=\frac{F \cdot d x}{d A} \quad\left(\mathrm{FL}^{-1}=\mathrm{MT}^{-2}\right. \end{aligned} \] \(\therefore\) Dimension of surface tension…
