Question
When a charged body is brought near an electroscope:
✓

Answer

  1. The strips of foils opens up.
Explanation:
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.
