Two protons are kept at a separation of 10 ~nm . Let F_ n and F_ e the nuclear force and the electromagnetic force between them
Options
- AF_ e =F_ n
- BF_ e F_ n
- CF_ e < F_ n
- DF_ e and F_ n differ only slightly
Correct answer
B. F_ e F_ n
Step-by-step solution
The nuclear forces are short range forces in range of few fm (ferrometre). whereas, electromagnetic force are long range forces. So, at a separation of 10 ~nm , the electromagnetic force is greater than the nuclear force between two protons, i.e. F_ e F_ n
