Write dimension of permeability of vacuum.

Options

A. `M^(1)L^(1)T^(-2)A^(-2)`
B. `M^(0)L^(1)T^(1)`
C. `M^(0)L^(2)T^(-1)A^(2)`
D. None of these

Explanation

From ampere circuital law force two parallel wire carry current I, and I, respectively. Force acting per unit length when they separated by distance g given by.
`(F)/(l)=(mu_(0)I_(1)I_(2))/(2piy) rArr u_(0)=(Fxx2pi y)/(lxxl_(1)I_(2))`
`:. [ mu_(0)]=([F]xx[y])/([l]xx[I_(1)][I_(2)])" " [ :. 2pi` dimension
`:. [mu_(0)]=((M^(1)L^(1)T^(-2))(L^(1)))/((L^(1))(A^(1))(A^(1)))=M^(1)L^(1)T^(-2)A^(-2)`
