Dimensions of `1/(sqrt(mu_0 in_0))` are

A

`[L^(-1)T]`

B

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

C

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

D

`LT^(-1)`

Text Solution

Verified by Experts

The correct Answer is:
C
We know that speed of em wave is `c=(1)/(sqrt(mu_(0)epsilon_(0)))`
`:.c^(2)=(1)/(mu_(0)epsilon_(0))`
`:.`Dimensions of `(1)/(mu_(0)epsilon_(0))=[L^(2)T^(-2)]`
Hence correct choice is `( c)`.
