B) \[\text{ }\!\![\!\!\text{ }{{\text{M}}^{\text{1}}}{{\text{L}}^{0}}{{\text{T}}^{\text{-2}}}\text{ }\!\!]\!\!\text{ }\]
C) \[\text{ }\!\![\!\!\text{ }{{\text{M}}^{\text{-1}}}{{\text{L}}^{2}}{{\text{T}}^{\text{-1}}}\text{ }\!\!]\!\!\text{ }\]
D) \[\text{ }\!\![\!\!\text{ }{{\text{M}}^{\text{-1}}}{{\text{L}}^{2}}{{\text{T}}^{\text{-2}}}\text{ }\!\!]\!\!\text{ }\]
Correct Answer: B
Solution :
Surface tension \[=\frac{F}{l}=\frac{[ML{{T}^{-2}}]}{[L]}\] \[=[{{M}^{1}}{{L}^{0}}{{T}^{-2}}]\]
