# Calculate the $V_{RMS}$ of organ atoms at room temperature $25^{\large\circ}$

$\begin{array}{1 1}(A)\;860m/s\\(B)\;430m/s\\(C)\;530m/s\\(D)\;265m/s\end{array}$

$C_{RMS}=\sqrt{\large\frac{3RT}{\mu \omega}}$
$\Rightarrow \sqrt{\large\frac{3\times 83\times (273+25)}{0.04}}$
$\Rightarrow 430.7cm/s$
Hence (B) is the correct answer.
