Question
If a body is charged by rubbing, its weight:
- Increases
- Decreases
- Can increase or decrease
- Cannot say
Hint:
The bodies gain or lose electrons. When a body is charged by rubbing, its weight may increase or decrease slightly.
The correct answer is: Can increase or decrease
When a body is charged by rubbing, its weight can increase or decrease.
- When the body is charged by rubbing, there are chances to gain or lose electrons.
- The weight of a body increases when it gains electrons.
- The weight of the body decreases as it loses electrons.
- Thus, there will be a slight increase or decrease in the weight of the body when it is rubbed.
