A) \[{{M}^{1}}{{L}^{0}}{{T}^{-2}}\]
B) \[{{M}^{0}}{{L}^{1}}{{T}^{-1}}\]
C) \[{{M}^{1}}{{L}^{1}}{{T}^{-2}}\]
D) \[{{M}^{1}}{{L}^{0}}{{T}^{-1}}\]
Correct Answer: A
Solution :
\[W=\frac{1}{2}k{{x}^{2}}\Rightarrow [k]=\frac{[W]}{[{{x}^{2}}]}=\left[ \frac{M{{L}^{2}}{{T}^{-2}}}{{{L}^{2}}} \right]=[M{{T}^{-2}}]\]
