If the ratio of vapour density for hydrogen and oxygen is `1/(16)`, then under constant pressure the ratio of their r.m.s velocities will be

A

`4/1`

B

`1/4`

C

`1/(16)`

D

`(16)/1`

Text Solution

Verified by Experts

The correct Answer is:
A
`v_(rms)=sqrt((3p)/(rho)) implies (v_1)/(v_2)=sqrt((rho_2)/(rho_1))=sqrt((16)/(1))=4/1`
