Two bodies of masses 3 m and 6 m have some momentum Their respective kinetic encics `E_1` and `E_2` are in the ratia

A

`1:2`

B

`2:1`

C

`sqrt2:1`

D

`1:1`

Text Solution

Verified by Experts

The correct Answer is:
B
As we know that E=`(P^2)/(2m)implies E prop 1/m`
`therefore (E_1)/(E_2)=(m_2)/(m_1)=(6m)/(3m)=2/1`
