Two bodies of masses m and 4 m are moving with equal kinetic energies. The ratio of their linear momenta is

A

`1 : 2`

B

`1 : 4`

C

`4 : 1`

D

`1 : 1`

Text Solution

Verified by Experts

The correct Answer is:
A
p `alpha` M (for same kinetic energy)
`(p_(1))/(p_(2))=sqrt((m_(1))/(m_(2)))=sqrt((m)/(2m))=1:2`
