A neutral object can be attracted to a charged rod because the rod causes:
AA permanent ionisation
BInduced polarization
CA complete discharge
DA change in its mass
Answer & Solution
Correct answer: B. Induced polarization
1. A neutral object still contains both kinds of charge.
2. Neutral objects contain equal quantities of positive and negative charge.
3. A nearby charge produces a slight shift in the electron distribution.
4. Unlike charges are brought nearer and like charges moved away.
5. This induced polarization leaves a net attraction to the rod.
