MCQ
Dimension of magnetic field is :
- ✓$I^{-1}ML^{0}T^{-2}$
- B$I^{0}MLT^{-2}$
- C$IMLT^{-1}$
- D$IM^{-1}L^{-1}T^{-2}$
✓
Answer
Correct option: A.
$I^{-1}ML^{0}T^{-2}$
(A) $I^{-1}ML^{0}T^{-2}$
[Hint : $F =q v B \Rightarrow B = F / q_V $
$ {[B] } =\frac{[ F ]}{[q][v]} $
$ =\frac{\left[ MLT ^{-2}\right]}{[ IT ]\left[ LT ^{-1}\right]}= I ^{-1} ML ^0 T^{-2}$
[Hint : $F =q v B \Rightarrow B = F / q_V $
$ {[B] } =\frac{[ F ]}{[q][v]} $
$ =\frac{\left[ MLT ^{-2}\right]}{[ IT ]\left[ LT ^{-1}\right]}= I ^{-1} ML ^0 T^{-2}$
