Which of the following basic forces can provide an attraction between two neutrons?
Correct answer: B. Gravitational and strong nuclear
- A. Electrostatic and nuclear
- B. Gravitational and strong nuclear
- C. Electrostatic and gravitational
- D. Only nuclear force
Explanation
The only fundamental force that can provide attraction between two neutrons over short distances is the strong nuclear force. The gravitational attraction also exists between them, but it's extremely weak on the scale of subatomic particles. The other forces, such as electrostatic and electromagnetic, do not apply to neutrons due to their lack of charge.

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.
