Two masses of 4 kg and 9 kg are moving with equal kinetic energies. The ratio of magnitudes of their linear momenta is:

A

`sqrt2:1`

B

`4:9`

C

`2:3`

D

`4:1`

Text Solution

Verified by Experts

The correct Answer is:
c
`(p_(1))/(p_(2))=sqrt((2m_(1)E)/(2m_(2)E))=sqrt((m_(1))/(m_(2)))=sqrt(4/9)=2/3`
