Nuclei

Question:

Two protons exerts a nuclear force on each other, the distance between them is

Options:

$10^{-14} \mathrm{~m}$

$10^{-10} \mathrm{~m}$

$10^{-12} \mathrm{~m}$

$10^{-8} \mathrm{~m}$

Correct Answer:

$10^{-14} \mathrm{~m}$

Explanation:

From the options, only at a distance of 10−14m the nuclear force will act. This is equal to ten Fermis, as 1 Fermi = 10−15m, and this falls within the short range within which it acts.
