STANDARD Physics Nuclear Forces MCQ Question
Two protons are kept at a separation of 40Å. Fₙ is the nuclear force and Fₑ is the electrostatic force between them. Then
Fₙ << Fₑ
Fₙ ≈ Fₑ
Fₙ >> Fₑ
Fₙ = Fₑ
Correct Answer
Detailed Explanation
Nuclear force is much stronger than the electrostatic force inside the nucleus, but at 40 Å, nuclear force is ineffective, and only electrostatic repulsion is present. Thus, Fₙ << Fₑ.
