Two particles of masses 4 kg and 9 kg possess kinetic energies in the ratio `9/4`. The ratio of their linear momenta will be

A

`1:1`

B

`4:9`

C

`2:3 `

D

`16:81`

Verified by Experts

The correct Answer is:

A

As, `p^2 = 2mk`
`(p^2)/(p_2^2) = (2m_1 k_1)/(2m_2k_2) = 4/9 xx 9/4 = 1/1`
`(p_1)/(p_2) = 1:1`
