Dimensions of surface tension are
A. ML0T2
B. ML0T-2
C. ML1T-2
D. ML-1T-2
Answer: Option C
Solution(By Examveda Team)
Surface tension is defined as the force acting per unit length along the line where two fluids meet or along the boundary of a fluid and a solid. The dimensional formula for surface tension is given by ML1T-2., where M represents mass, L represents length, and T represents time.Therefore, the correct answer is Option C: ML1T-2.

The difference of pressure between the inside and outside of a liquid drop is
A. $${\text{p}} = {\text{T}} \times {\text{r}}$$
B. $${\text{p}} = \frac{{\text{T}}}{{\text{r}}}$$
C. $${\text{p}} = \frac{{\text{T}}}{{2{\text{r}}}}$$
D. $${\text{p}} = \frac{{2{\text{T}}}}{{\text{r}}}$$
A. cannot be subjected to shear forces
B. always expands until it fills any container
C. has the same shear stress.at a point regardless of its motion
D. cannot remain at rest under action of any shear force
MT−2
Answer B
Surface tention = N/m
N= Newton
M= meter
N= kg.m/sec^2=M^1 L^1 T^-2] /M=[L^-1] Therefore, surface tension is dimensionally represented as M^1L^° T^-2.
