Question
A neutron exerts a force on a proton which is:
  1. Gravitational.
  2. Electromagnetic.
  3. Nuclear.
  4. Weak.

Answer

  1. Gravitational
  1. Nuclear
Explanation:
A neutron exerts both the gravitational and nuclear forces on a proton.
The gravitational force can be seen between a neutron and a proton. However, its strength is negligible. The nuclear force is exerted only if the interacting particles are neutrons or protons or both. A neutron cannot exert electromagnetic force, because it is a neutral particle.
