The question "Who is the MR of neutron?" is unclear. "MR" could potentially refer to a few different things. Here are some possible interpretations and corresponding answers:
Interpretation 1: MR as in "Mass in kg" or "Mass Relative to the Atomic Mass Unit (Da)"
If "MR" is intended to mean "Mass," then the answer is: The mass of a neutron is approximately 1.674927471 × 10−27 kg, or 1.00866491588 Da (Daltons). This refers to the mass of a free neutron.
Interpretation 2: MR as in "Magnetic Resonance" or "Magnetic Moment"
If "MR" is intended to mean something related to magnetic resonance, it likely refers to the neutron's magnetic moment. In this case, the answer is: A neutron possesses a magnetic moment despite being electrically neutral. Its value is approximately -9.6623651(23) × 10−27 J⋅T−1 (Joules per Tesla). The negative sign indicates that the magnetic moment is antiparallel to the neutron's spin.
Interpretation 3: MR as an unknown abbreviation.
It's possible "MR" refers to a completely different context that is not provided. Without further information, it is impossible to accurately answer what "MR" represents.
In summary, the response addresses the most plausible interpretations of "MR" related to a neutron.
