Which statement about a neutron's electric charge is true?

• A. Negative charge
• B. No charge
• C. Positive charge
• D. Variable charge

Answer: (B)

The important idea here is electrical neutrality. A neutron has no net electric charge, so it is electrically neutral. This means it does not feel electric forces in an external electric field, unlike a proton (positive) or an electron (negative). The charge of a neutron is fixed at zero; saying it has a negative or positive charge would be incorrect, and claiming its charge can vary isn’t accurate for a fundamental particle.
