30c) less than one..
K.E. = p2/2m
Since they both have same linear momentum..
The ratio of their K.E.s = mb/mr
Hence, the value is less than one..
1@ashish .....
u cant say that the linear momentum of both bullet and gun are same but their sum is conseved.....and \comin to answer of the ques it is (c)in general if mass of bullet is greter than mass of gun.....
1no harsha linear momenta will be same .as there momenta is equal but in opposite direction.then there sum will be zero.
71Nothing great in re posting the same thing. If anyone has doubt then only Post.

yes u r right and i was thnkn it in diffrnt way and ur answer is a kinda of correct but actaually the squares of momenta is same............
