MCQ
The short range attractive nuclear forces that are responsible for the binding of nucleons in a nucleus are supposed to be caused by the role played by the particles called:

- C$K-$Meson
- ✓$\pi-$ Meson
✓
Answer
Correct option: D.
$\pi-$ Meson
The nuclear force between a neutron and proton is the result of the exchange of charged mesons $(\pi^+\pi^-)$ between them.
