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) :

Answer»

`OMEGA k`
`vlambda`
`sqrt(epsi_(0)mu_(0))`
`sqrt(P/rho.)`

Solution :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).`
