Complete the following sentence: 

When a charged body is brought near an electroscope:

• 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 a similar charge, those repel each other and thus open up.

Therefore, we can say that when a charged body is brought near an electroscope, the metal stripes become wide open.
