The permeability of a substance is `3pi xx10^(-3)` Tm/A what is its relative permeability ? [`mu_(0)=4pixx10^(-7)`]

A

`7.5 xx10^(+4)`

B

`7.5xx10^(+3)`

C

`5xx10^(+4)`

D

`5xx10^(+3)`

Text Solution

Verified by Experts

The correct Answer is:
B
`mu_(R )=(mu)/(mu_(0))=(3pixx10^(-3))/(4pixx10^(-7))=7.5 xx10^(3)`
