Which of the following does not have the dimensions of velocity ? (Given, `epsilon_(0)` = permittivity of free space, `mu_(0)` = permeability of free space, `v` = frequency , is the wavelength, `P` is the pressure and = density, `k` = wave number, `omega` is the angular frequency) :

A

`omega k`

B

`vlambda`

C

`sqrt(epsi_(0)mu_(0))`

D

`sqrt(P/rho.)`

Text Solution

Verified by Experts

The correct Answer is:
A
Here `omegaxxk=T^(-1)L^(-1)` which are not the dimensions of velocity . All others have got the dimensions of velocity.
Hence correct choice is `(a).`
