The rms velocity of smoke particles of mass `3 xx 10^(-17) kg. at 27^(@)C` in m/sec. is.

Explanation

To find the root mean square (rms) velocity of smoke particles, we will use the formula derived from the kinetic theory of gases:

\[ V_{rms} = \sqrt{\frac{3kT}{m}} \]

where:
- \( V_{rms} \) = root mean square velocity
- \( k \) = Boltzmann constant \( = 1.38 \times 10^{-23} \, \text{J/K} \)
- \( T \) = absolute temperature in Kelvin
