Two sample of gases A and B are at the same temperature. The molecules of A are travelling 4 times faster than molecules of B. The ratio `M_(A) //M_(B)` of their masses will be

A

16

B

`1//16`

C

4

D

`11/4`

Text Solution

Verified by Experts

The correct Answer is:
B
`(r_(A))/( r_(B)) = sqrt((M_(B))/(M_(A)))`
`4 = sqrt((M_(B))/(M_(A)))`
or `sqrt(( M_(A))/( M_(B))) = ( 1)/( 16)`
