Question

Two protons are kept at a separation of 10 nm. Let F_n and F_e be the nuclear force and the electromagnetic force between them ____________.

Options

• F_e << F_n

• F_e = F_n

• F_e and F_n differ only slightly

• F_e >> F_n

Answer 1

Two protons are kept at a separation of 10 nm. Let F_n and F_e be the nuclear force and the electromagnetic force between them F_e >> F_n.

Explanation:

For distances greater than femtometre (10^-15 m) the nuclear forces are not effective.

Hence, F_e >> F_n.
