A) \[M{{L}^{-1}}{{T}^{-2}}{{Q}^{-2}}\]
B) \[M{{L}^{2}}{{T}^{-2}}{{Q}^{-2}}\]
C) \[ML{{T}^{-2}}{{Q}^{-1}}\]
D) \[M{{L}^{2}}{{T}^{-2}}{{Q}^{-1}}\]
Correct Answer: D
Solution :
\[e=L\frac{di}{dt}\Rightarrow [e]=[M{{L}^{2}}{{T}^{-2}}{{A}^{-2}}]\,\left[ \frac{A}{T} \right]\] \[[e]=\left[ \frac{M{{L}^{2}}{{T}^{-2}}}{AT} \right]=[M{{L}^{2}}{{T}^{-2}}{{Q}^{-1}}]\]
