The existence of a negative charge on a body implies that it has:

• A. lost some of its electrons
• B. lost some of its atoms
• C. acquired some electrons from outside
• D. acquired some protons from outside

The presence of a negative charge on an object indicates that it has gained extra electrons. This is because electrons carry a negative charge, and when an object acquires more of them, it becomes negatively charged.

Understanding Charge

In the context of electric charge, here’s a breakdown of the options:

• A. Lost some of its electrons: This would make the object positively charged, not negatively charged.
• B. Lost some of its atoms: Atoms consist of protons, neutrons, and electrons; losing atoms doesn't directly relate to charge.
• C. Acquired some electrons from outside: This is the correct answer, as gaining electrons results in a negative charge.
• D. Acquired some protons from outside: Protons are positively charged, so gaining them would lead to a positive charge.

Final Thoughts

Thus, the correct answer is C. acquired some electrons from outside, which explains the negative charge on the body.
