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

A

`1 : 9`

B

` 9 : 1`

C

`1 : 3`

D

`3 : 1`

Text Solution

Verified by Experts

The correct Answer is:

c

`p = sqrt(2mE), p_(1)//p_(2) = sqrt(m_(1)//m_(2)) = sqrt(1//9) = 1//3`
