The dimension of magnetic field in M,L,T\mathrm{M}, \mathrm{L}, \mathrm{T} and C\mathrm{C} (Coulomb) is given as

Options

  1. AMLT−1C−1\mathrm{MLT}^{-1} \mathrm{C}^{-1}
  2. BMT2C−2\mathrm{MT}^2 \mathrm{C}^{-2}
  3. CMT−1C−1\mathrm{MT}^{-1} \mathrm{C}^{-1}
  4. DMT−2C−1\mathrm{MT}^{-2} \mathrm{C}^{-1}

Correct answer

C. MT−1C−1\mathrm{MT}^{-1} \mathrm{C}^{-1}

Step-by-step solution

F=qvBB=F/qv=MC−1T−1\begin{aligned} & F=q v B \\ & B=F / q v=M C^{-1} T^{-1} \end{aligned}
