Two masses of 1 kg and 9 kg are moving with equal kinetic energies. What is the ratio of the magnitudes of their respective linear momenta?

A

`1:9`

B

`3:1`

C

`9:1`

D

`1:3`

Verified by Experts

The correct Answer is:

D

`P=sqrt(2Km) i.e, P alpha sqrtm, ` K is same for both. `P_(1)/P_(2)=(m_(1))/(m_(2))= sqrt(1/4) =1/2`
