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

Answer

B

Explanation

`dF=(dq)(lambda/(2pi in_(0)R))=((qdtheta)/pi)(lambda/(2pi in_(0)R))`
`F_("net")=underset(0)overset(pi//2)(int)2dF cos theta=(qlambda)/(pi^(2) in_(0)R)`
`rArr underset(0)overset(pi//2)(int) cos theta d theta=(qlambda)/(pi^(2) in_(0)R)`
