The charge acquired by a glass rod when it is rubbed with a silk isa)negativeb)positivec)bothd)none.Correct answer is option 'B'. Can you explain this answer?

Question

Answer

When you are rubbing the glass rod with the silk cloth, electrons are stripped away from the atoms in the glass and transferred to the silk cloth. This leaves the glass rod with more positive than negative charge, so you get a net positive charge.

Answer

When glass rod is rubbed with silk, glass happens to lose electrons easily and silk grabs them away from the glass atoms. So after rubbing, the glass becomes positively charged and the silk becomes negatively charged. Thus equal but opposite charge are produced on the both.....

Answer

When you are rubbing the glass rod with the silk cloth, electrons are stripped away from the atoms in the glass and transferred to the silk cloth. This leaves the glass rod with more positive than negative charge, so you get a net positive charge.

Answer

Understanding Charge Transfer
When a glass rod is rubbed with silk, a transfer of electrons occurs between the two materials. This phenomenon is a classic example of static electricity.
Process of Rubbing
- Electron Movement: When rubbing occurs, electrons (which carry a negative charge) are transferred from the glass rod to the silk.
- Material Properties: Glass has a tendency to lose electrons, while silk tends to gain electrons.
Resulting Charges
- Glass Rod: After losing electrons, the glass rod becomes positively charged.
- Silk: In contrast, the silk gains those electrons and becomes negatively charged.
Why is the Charge Positive?
- Positive Charge Definition: A positive charge indicates a deficiency of electrons. Since the glass rod has lost electrons, it has more protons than electrons, resulting in a positive charge.
- Common Observations: This behavior aligns with the triboelectric series, which ranks materials based on their tendency to gain or lose electrons.
Conclusion
The correct answer to the question of what charge a glass rod acquires when rubbed with silk is positive. The glass rod's loss of electrons during this interaction leads to its positive charge, while the silk becomes negatively charged.
Understanding this concept is essential for grasping the basics of static electricity and charge interactions!
