Two masses of 1 gm and 4 gm are moving with equal kinetic energies. The ratio of the magnitudes of their linear momenta is

A

`4:1`

B

`sqrt2:1`

C

`1:2`

D

`1:16`

Text Solution

Verified by Experts

The correct Answer is:
C
`P=sqrt(2mE)`. If E are same then `P prop sqrt(m)`
`rArr (P_(1))/(P_(2))=sqrt((m_(1))/(m_(2)))=sqrt((1)/(4))=(1)/(2)`
