As we learnt in

Magnetic induction(B) -

$\dpi{100} M^{1}L^{0}T^{-2}A^{-1}$

- wherein

$\dpi{100} \frac{newton }{ampere - metre },\frac{volt -second }{metre^{2}}$

Lorentz force $=\left | \vec{F} \right |=\left | q\vec{v}\times\vec{B} \right |$

$\therefore\ [B]=\frac{[F]}{[q][v]}=\frac{MLT^{-2}}{C\times LT^{-1}}=\frac{MLT^{-2}}{CLT^{-1}}=[MT^{-1}C^{-1}]$

Option 1)

MT-2C-1

This is an incorrect option.

Option 2)

MLT-1C-1

This is an incorrect option.

Option 3)

MT2C-2

This is an incorrect option.

Option 4)

MT-1C-1

This is the correct option.
