A wire of length $\displaystyle 30$ cm , stretched between rigid supports, has it's $\displaystyle \mathrm{n}^{\text {th }}$ and $\displaystyle (\mathrm{n}+1)^{\text {th }}$ harmonics at $\displaystyle 400$ Hz and $\displaystyle 450$ Hz , respectively. If tension in the string is $\displaystyle 2700$ N , it's linear mass density is \_\_\_\_ kg/m.
