Question

When a glass rod is rubbed with silk, electrons move from silk to glass rod, thereby the glass rod gets positively charged and the silk negatively charged.

• A. True
• B. False

Answer 1

The correct option is B False

1. If any two substances in this list are rubbed against one another, the one higher in the order gets positively charged and the other will get a negative charge.
2. Glass when rubbed with silk, acquires a positive charge because glass has a higher frictional order than silk.
3. Glass acquires a positive charge because electrons will move to silk, due to a deficiency of electrons glass will acquire a positive charge.
4. And silk will acquire a negative charge due to excess electrons.

Hence, the given statement is false.
