The dimensions of permeability of free space can be given by

A

`[MLT^(-2)A^(-2)]`

B

`[MLA^(-2)]`

C

`[ML^(-3)T^(2)A^(2)]`

D

`[MLA^(-1)]`

Text Solution

Verified by Experts

The correct Answer is:
A
Force per unit length between two parallel current carrying conductor
`F=(mu_(0))/(4pi)(2I_(1)I_(2))/d N//m`
`N/m=mu_(0)/(4pi)(Amp^(2))/m implies mu_(0)=N/Amp^(2)`
`[mu_(0)]=[MLT^(-2)A^(-2)]`
