In the relation P = `alpha/beta overline(e) (alpha z)/(k theta), ` p is pressure z the distance , k is Boltzmann constant and `theta` is the temperature , the dimensional formula of `beta` will be .
Sol. In Given equation , `(alpha z)/(k theta)` should be dimensinless.
`:.` `alpha = (k theta)/(z)`
`rArr [a] = ([ML^2 T^-2 K^-1 xx K])/([L])` = `[MLT^-2]`
and `P = alpha/beta`
`rArr [beta] = [alpha/p] = ([MLT^-2])/([ML^-1T^-2])`
= `[M^0L^2T^0]`
