Two protons are kept at a separation of 40 Å F_ n is the nuclear force and F_ is the electrostatic force between them. Then,

Options

  1. AF_ n < < F_ e
  2. BF_ n F_ e
  3. CF_ n >F_ e
  4. DF_ n =F_ e

Correct answer

C. F_ n >F_ e

Step-by-step solution

Nuclear force F_ n are attractive in nature. As in the given case, the two protons are kept at a separation of 40 Å (short range), hence in this range, nuclear force F_ n is much greater than the electrostatic force F_ e . i.e. F_ n F_ e
