Two bodies of masses m and 2m have same momentum. Their respective kinetic energies `E_(1 )` and `E_(2)` are in the ratio

A

`1:2`

B

`2:1`

C

`1:sqrt2`

D

`1:4`

Text Solution

Verified by Experts

The correct Answer is:
B
`E=(P^(2))/(2m)`. If momentum are same then `E prop (1)/(m)`
`therefore (E_(1))/(E_(2))=(m_(2))/(m_(1))=(2m)/(m)=(2)/(1)`
