A bomb at rest explodes into 3 parts of ...

A bomb at rest explodes into 3 parts of the same mas. The momenta of the two parts are `-2p hati`and `phatj`. What is the magnitude of the momentum of the third part?

A

`sqrt(3)p`

B

`sqrt(5)p`

C

`sqrt(P)`

D

`sqrt(7)p`

Text Solution

Verified by Experts

The correct Answer is:
B
Initial momentum of the moving body=mv and that of the stationary body= 0
After striking , their combind mass =3 m
`therefore` From the law of conservation of linear momentum
`mv+0=(m+2m)v'`
`thereforev'=(mv)/(3m)=v/3`
