When we rub a glass rod with a silk cloth then________________?
Correct answer: B. glass rod acquires positive charge while silk acquires negative charges
- A. glass rod acquires negative charge while silk acquires positive charge
- B. glass rod acquires positive charge while silk acquires negative charges
- C. both glass rod and silk acquire negative charge
- D. both glass rod and silk acquire positive charge
Explanation
Rubbing transfers electrons from the glass to the silk. The glass therefore becomes positively charged and the silk negatively charged, with equal and opposite charges ideally produced.
