MCQ
What happens when a glass rod is rubbed with silk?
- ✓Gains protons from silk.
- BGains electrons from silk.
- CGives electrons to silk.
- DGives protons to silk.
✓
Answer
Correct option: A.
Gains protons from silk.
Excess electrons are transferred from glass to silk when a glass rod is rubbed with silk. Hence, the glass rod becomes positive, and silk becomes negative.
