A positively charged glass rod attracts an object. The object must be :
- A negatively charged
- B neutral
- C either negatively charged or neutral
- D a magnet
Answer & Solution
Correct Answer
(C) either negatively charged or neutral
Step-by-step Solution
Detailed explanation
Attraction occurs with opposite charges (negative) due to Coulomb's Law. It also occurs with neutral objects because the rod's positive field induces a charge separation (polarization) in the object, creating a net attractive force. C) either negatively charged or neutral.
