Dimensions of in(0)mu(0) are :...

Dimensions of `in_(0)mu_(0)` are :

A

`[LT^(-1)]`

B

`[LT^(-2)]`

C

`[L^(2)T^(-2)]`

D

`[L^(-2)T^(2)]`

Text Solution

Verified by Experts

The correct Answer is:
D
We know that speed of e.m. wave is `C=(1)/(sqrt(mu_(0)epsilon_(0)))`
`:. mu_(0)epsilon_(0)=(1)/(C^(2))=L^(-2)T^(2)`
Hence correct choice is `(d)`.
