  1. A.MLT-1C-1
  2. B.MT2C-2
  3. C.MT-1C-1correct
  4. D.MT-2C-1

Answer

C. MT-1C-1

Explanation

We know that, Lorentz force $$\left| {\overrightarrow F } \right| = \left| {q\overrightarrow v \times \overrightarrow B } \right|$$ $$\therefore [B] $$ = $${[F] \over {[q][v]}}$$ = $${[{ML{T^{ - 2}}]} \over {[C] \times [L{T^{ - 1}}]}}$$ = [$$M{T^{ - 1}}{C^{ - 1}}$$]
