Root mean square velocity of a gas molecule is proprotional to

A

`m^(1//2)`

B

`m^(0)`

C

`m^(-1//2)`

D

`m`

Text Solution

Verified by Experts

The correct Answer is:
C
Root mean square speed is given by the expression
`U_("rms")=sqrt((3RT)/(M))" "[becauseM=mN]`
`therefore" "U_("rms")propsqrt((1)/(m))`
`rArr" "u_("rms")prop(m)^(-1//2)`
