A 9 kg mass and 4kg mass are moving with equal kinetic energies. T he ratio of their momentum is

A

`1 :1`

B

`3:2`

C

`2:3`

D

`9:4`

Text Solution

Verified by Experts

The correct Answer is:
B
Given that K.E. are equal `therefore p_(1)^(2)/(2m_(1))=p_(2)^(2)/(2m^(2)) therefore p_(1)/p_(2)=sqrt(m_(1)/m_(2))=sqrt(9/4)=3/2`
