Question

If an ebonite rod rubbed with fur and a glass rod rubbed with silk cloth are brought nearer to each other, then what happens?

• A. They will attract each other.
• B. They will repel each other.
• C. Nothing will happen to them.
• D. They will get heated up.

Answer 1

The correct option is A They will attract each other.

On rubbing the ebonite rod with fur, electrons move from fur to the ebonite rod. Hence, the ebonite rod becomes negatively charged.

When the glass rod is rubbed with silk cloth, glass quickly loses electrons and silk takes electrons. Hence, the glass rod becomes positively charged.

Since, unlike charges attract each other. Hence, if an ebonite rod rubbed with fur and a glass rod rubbed with silk cloth are brought closer to each other, they will attract each other.
