Question: Answered & Verified by Expert
Two protons are kept at a separation of \( 10 \mathrm{~nm} \). Let Fn and Fe be the nuclear force and the
electromagnetic force between them
PhysicsNuclear PhysicsKCETKCET 2019
Options:
  • A \( \mathrm{Fe}< < \mathrm{F} \)
  • B \( \mathrm{Oe}=\mathrm{Fn} \)
  • C Fe and Fn differ only slightly
  • D \( \mathrm{Fe} \gg \mathrm{Fn} \)
Solution:

The correct answer is: \( \mathrm{Fe} \gg \mathrm{Fn} \)
(D)
As separation is less than \( f m \), electromagnetic force is greater than nuclear force. Fe >> Fn.
[Nuclear force is short range force acts. Within few fms]
