A gas consists of 5 molecules with a velocity of `5ms^(-1)` , 10 molecules with a veclocity of `3ms^(-1)` and 6 molecules with a velocity of `6ms^(-1)`. The ratio of average velocity and rms velocity of the molecles is `9.5xx10^(-x)` Where `x` is……….

Text Solution

Verified by Experts

The correct Answer is:
1

Average velocity `=(5xx5+10xx3+6xx6)/21=4.33`
rms velocity `=sqrt((5xx25+10xx9+6xx36)/21)=4.53`
`(V_(av))/(V_("rms"))=0.955=9.5xx10^(-1)`
`x=1`
