The dimensional formula of `sqrt(mu_r epsi_r)` is _________

A

`M^?1 L^(-1) T^(-2) A^(-1)`

B

`M^1 L^1 T^(-2) A^0`

C

`M^0 L^0 T^0 A^0`

D

`M^0 L^2 T^(-2) A^0`

Text Solution

Verified by Experts

The correct Answer is:
C
`v = 1/(sqrt(mu_0 epsi_0 mu_r epsi_r)) = (c)/(sqrt(mu_r epsi_r))`
`sqrt(mu_r epsi_r) = c/v `= Dimensionless.
