What happens when an ebonite rod rubbed with fur and a glass rod rubbed with silk are brought near each other?
- ✓They attract each other.
- BThey repel each other.
- CNothing happens to them.
- DThey acquire heat.
Answer
View full question & answer→Correct option: A.
They attract each other.
The charge on the ebonite rod rubbed with fur is negative $($as it gains electrons$)$. The charge on the glass rod rubbed with silk is positive $($as it loses electrons$)$. So, when these two rods are brought close to each other, they attract, since unlike charges attract each other.
