Which of the three basic forces gravitational, electrostatic, and nuclear is/are able to provide an attraction between two neutrons?
Correct answer: D. only nuclear
- A. electrostatic and nuclear
- B. electrostatic and gravitational
- C. gravitational and nuclear
- D. only nuclear
Explanation
D is the right option because Neutrons do not possess electric charge, so they do not experience electrostatic forces. Gravitational forces between neutrons are extremely weak and can generally be neglected in nuclear interactions. The only force capable of providing an attraction between two neutrons is the strong nuclear force, which operates within the nucleus.

About Nuclear Physics
Atomic nuclei contain protons and neutrons, with nuclear size, mass defect and binding energy describing their stability. The work covers alpha, beta and gamma decay, decay equations, half-life and decay rate, along with radiation safety and medical applications such as imaging, radiotherapy and tracers.
