The mass of two substance are `4 gm and 9 gm` respectively. If their kinetic energy are the same, then the ratio of their momrntum will be

A

`4:9`

B

`9:4`

C

`3:2`

D

`2:3`

Text Solution

Verified by Experts

The correct Answer is:
D
`P=sqrt(2mE)rArr (P_(1))/(P_(2))=sqrt((m_(1))/(m_(2)))=sqrt((4)/(9))=(2)/(3)`
