Question

The dimension of magnetic field in M, L, T and C (coulomb) is given as

• A MLT^-1C^-1
• B MT²C^-2
• C MT^-1C^-1
• D MT^-2C^-1

Answer 1

Correct option is C) MT^-1C^-1

We know that,
Lorentz force $\left|\overrightarrow{F}\right|=\left|q\overrightarrow{v}\times \overrightarrow{B}\right|$

$\therefore [B]=\frac{[F]}{[q][v]}=\frac{[ML{T}^{-2}]}{[C]\times [L{T}^{-1}]}=[M{T}^{-1}{C}^{-1}]$
