The correct answer to the question "Which of the following does not serve as a way to neutralize the charge in a body?" is:
D. Adding more protons to a positively charged body until the number of protons matches the number of electrons
Explanation:
1. Allowing free electrons to escape from a negatively charged body can neutralize the charge because when electrons escape, the body loses negative charge, making it less negatively charged.
2. Bringing the charged body into contact with another body having an equal but opposite charge can neutralize the charge. For example, if a negatively charged body is brought into contact with a positively charged body, electrons can flow between them until they reach equilibrium, neutralizing the charge.
3. Adding free electrons to a positively charged body can neutralize the charge by increasing the number of negative charges, balancing the positive charge present.
4. However, adding more protons to a positively charged body until the number of protons matches the number of electrons will not neutralize the charge. Protons are positively charged particles, and adding more protons to a positively charged body would only increase the positive charge, not neutralize it.
In summary, options A, B, and C provide ways to neutralize the charge in a body, while option D does not serve as a way to neutralize the charge.
