Question
When a glass rod is rubbed with silk:
- Negative charge is produced on silk, but no charge is produced on the glass rod.
- Equal but opposite charges are produced on both the materials.
- Equal and similar charges are produced on both the materials.
- Positive charge is produced on the glass rod but no charge is produced on the silk.
Hint:
The charge is a property of matter.
The correct answer is: Equal but opposite charges are produced on both the materials.
When a glass rod is rubbed with silk: Equal but opposite charges are produced on both the materials.
- When the glass rod is rubbed with silk, the electrons from the rod strip away from the rod and move to the silk.
- Hence the rod gets positively charged.
- As the electrons are moved to the silk, it became negatively charged and the rod has a positive charge.
- The equal but opposite charges are produced in both materials.
