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

A $[MLT^{- 1} C^{- 1}]$
B $[MT^{2} C^{- 2}]$
C $[MT^{- 1} C^{- 1}]$
D $[MT^{- 2} C^{- 1}]$

Solution & Step-by-step Explanation

Force on a moving charge: F = q v B sin θ .Dimensions: [B] = \frac{[ F ]}{[ q ] [ v ]} = \frac{[ MLT ^{- 2} ]}{[ C ] [ LT ^{- 1} ]} [B] = [M] [C^{- 1}] [T^{- 2 + 1}] = [MT^{- 1} C^{- 1}]
