MCQ
When a charged body is brought near an electroscope:
- ✓The strips of foils opens up.
- BThe strips of foils close.
- CThe strips open and close simultaneously.
- DThe strips neither open nor close.
✓
Answer
Correct option: A.
The strips of foils opens up.
When a charged body is brought near the top conducting disc of an electroscope, the disc gets induced with charges. These charges run down to the metal strips hanging from the paper clip. Now as both the strips get similar charge, those repel each other and thus open up.
