Dimensional formula of magnetic field of induction (B) is:

Given Force on a charged particle is given by: $$F = qvBsin \theta$$ where $$\theta$$ is angle between velocity and magnetic field.


ANSWER

$$MT^{-2}I^{-1}$$


SOLUTION
It is given:
$$F=qvBsin \theta$$
Hence, $$B= \dfrac{F}{qvsin\theta}$$
Dimensional formula of magnetic field is:
$$[B] = [F/qv]$$ as $$sin \theta$$ is dimensionless
$$[B] = [MLT^{-2}][I^{-1}T^{-1}][L^{-1}T]$$
$$[B] = [MT^{-2}I^{-1}]$$
