Let \[[{{\varepsilon }_{0}}]\] denotes the dimensional formula of the permittivity of the vacuum and \[[{{\mu }_{0}}]\] that of the permeability of the vacuum. If \[M=\text{mass}\], \[L=\text{length}\], \[T=\text{Time}\] and \[I=\text{electric current}\], then [IIT 1998] |
A. | \[[{{\varepsilon }_{0}}]={{M}^{-1}}{{L}^{-3}}{{T}^{2}}I\] |
B. | \[[{{\varepsilon }_{0}}]={{M}^{-1}}{{L}^{-3}}{{T}^{4}}{{I}^{2}}\] |
C. | \[[{{\mu }_{0}}]=ML{{T}^{-2}}{{I}^{-2}}\] |
D. | \[[{{\mu }_{0}}]=M{{L}^{2}}{{T}^{-1}}I\] |
Answer» C. \[[{{\mu }_{0}}]=ML{{T}^{-2}}{{I}^{-2}}\] | |
