Question

Two protons are kept at a separation of 10 nm. Let Fn and Fe be the nuclear force and the electromagnetic force between them.
(a) Fe = Fn
(b) Fe >> Fn
(c) Fe << Fn
(d) Fe and Fn differ only slightly.

Answer 1

Two protons are kept at a separation of 10 nm. Let Fn and Fe be the nuclear force and the electromagnetic force is Fe >> Fn.

Explanation:

Let us consider that Fe and Fn be the electromagnetic force and the nuclear force. A repulsive electrostatic force and a strong attractive nuclear force is exerted on one another. It is to be understood that the nuclear forces are the short-ranged forces. So, at a 10 nm separation, the nuclear force is lesser than the electromagnetic force, that is, i.e. Fe >> Fn.
