A 4 kg mass and a 1 kg mass are moving with equal kinetic energies. The ratio of the magnitudes of their linear momenta is

A

`1:2`

B

`1:1`

C

`2:1`

D

`4:1`

Text Solution

Verified by Experts

The correct Answer is:

C

`P=sqrt(2mE)`. If E are const. then `(P_(1))/(P_(2))=sqrt((m_(1))/(m_(2)))=sqrt((4)/(1))=2`
