Two protons are kept at a separation of \(10 \mathrm{~nm}\). Let \(F_{n}\) and \(F_{e}\) the nuclear force and the electromagnetic force between them
- A \(F_{e}=F_{n}\)
- B \(F_{e} \gg F_{n}\)
- C \(F_{e} < F_{n}\)
- D \(F_{e}\) and \(F_{n}\) differ only slightly
Answer & Solution
Correct Answer
(B) \(F_{e} \gg F_{n}\)
Step-by-step Solution
Detailed explanation
The nuclear forces are short range forces in range of few \(\mathrm{fm}\) (ferrometre).
whereas, electromagnetic force are long range forces.
So, at a separation of \(10 \mathrm{~nm}\), the electromagnetic force is greater than the nuclear force between two protons, i.e.
\(F_{e} \gg F_{n}\)
whereas, electromagnetic force are long range forces.
So, at a separation of \(10 \mathrm{~nm}\), the electromagnetic force is greater than the nuclear force between two protons, i.e.
\(F_{e} \gg F_{n}\)
