Q79 / 105 · JEE Main 2008 · Physics
The dimension of magnetic field in $\mathrm{M}, \mathrm{L}, \mathrm{T}$ and $\mathrm{C}$ (Coulomb) is given as
- A$\mathrm{MLT}^{-1} \mathrm{C}^{-1}$
- B$\mathrm{MT}^2 \mathrm{C}^{-2}$
- Correct answerC$\mathrm{MT}^{-1} \mathrm{C}^{-1}$
- D$\mathrm{MT}^{-2} \mathrm{C}^{-1}$
Solution
$$
\begin{aligned}
& F=q v B \\
& B=F / q v=M C^{-1} T^{-1}
\end{aligned}
$$
Hence, the correct answer is option: 'C'.
