A block at rest explodes into 3 parts are `-2phatj and phatj`. Calculate the magnitude of the momentum of third part.

Text Solution

Verified by Experts

Let `vecP` be the momentum of the third particle after the explosion of bomb. According to law of conservation of momentum,`-2pvecj+pvecj+vecP``=0(or)vecP=2pveci-pvecj`
`P=sqrt(2p)^(2)+(-p)^(2)=psqrt5`
