Two protons are kept at a separation of 40 Å . F_ n is the nuclear force and F _ e 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
F _ n is stronger than F _ e . F _ n operates at very short range inside the nucleus as little as 10⁻¹⁵ ~m . As in the given case two protons are kept at a separation of 40 Å F _ n < F _ e .
