Using `mass (M), "length"(L) , time (T)` and current` (A) `as fundamental quantites the demension of permeability is

A

`[M^(-1)LT^(-2)A]`

B

`[ML^(-2)T^(-2)A^(-1)]`

C

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

D

`[MLT^(-1)A^(-1)]`

Text Solution

Verified by Experts

The correct Answer is:
C
` B = (mu_(0))/(2 pi) (i)/(r) `
but ` B = (F)/(il) (F= ilB)`:.
`(F)/(il) = (mu_(0))/(2 pi ) (i)/(r) `
` [mu_(0)] = [(F)/(i^(2))]`
