Two protons are kept at a separation of 40 Å F_ n is the nuclear force and F_ is the electrostatic force between them. Then,
Options
- AF_ n < < F_ e
- BF_ n F_ e
- CF_ n >F_ e
- DF_ n =F_ e
Correct answer
C. F_ n >F_ e
Step-by-step solution
Nuclear force F_ n are attractive in nature. As in the given case, the two protons are kept at a separation of 40 Å (short range), hence in this range, nuclear force F_ n is much greater than the electrostatic force F_ e . i.e. F_ n F_ e
