A $\pi^0$ at rest decays into $2 \gamma$ rays $\pi^0 \rightarrow \gamma+\gamma$. Then which of the following can happen |
The two $\gamma$'s move in same direction The two $\gamma$'s move in opposite direction Both repel each other Both attract each other |
The two $\gamma$'s move in opposite direction |
| Due to conservation of momentum two gamma particle are moving in opposite direction. |
