A) \[\left[ \text{ML}{{\text{T}}^{-1}}\text{A} \right]\]
B) \[\left[ {{\text{M}}^{2}}\text{L}{{\text{T}}^{-2}}{{\text{T}}^{-1}} \right]\]
C) \[\left[ \text{M}{{\text{T}}^{-2}}{{A}^{-1}} \right]\]
D) None of these
Correct Answer: C
Solution :
\[\vec{F}=q\,\vec{v}\times \vec{B}\] or \[F=q\,v\,B\sin \theta \] \[\therefore \] \[[B]=\left[ \frac{F}{qv} \right]=\frac{[ML{{T}^{-2}}]}{[AT][L{{T}^{-1}}]}\] \[=\,[M{{T}^{-2}}{{A}^{-1}}]\]You need to login to perform this action.
