What happens when we bring a positively charged rod close to an uncharged conductor?
Answer & explanation
Correct answer: option 3
The correct answer is Option 3: It is electrically neutral.
When a positively charged rod is brought near an uncharged conductor, the conductor undergoes electrostatic induction:
-
Free electrons inside the conductor rearrange — they are attracted toward the side near the rod, making that side negatively charged, and leaving the far side positively charged.
-
No net charge is transferred — the total charge on the conductor remains zero.
-
The conductor is now polarized, not charged.
However, unless the conductor is grounded (allowing charge to flow in or out), it does not acquire any net charge.
