Question

what will happen to the leaves of an electroscope if a positively charged body is brought near a negatively charged electroscope?​

Answer 1

When a negatively charged object is brought near an electroscope the charge will induce a positive charge on the leaves. So nothing should happen. If the object touches the electroscope the negative charge will discharge the leaves that have the positive charge. Then the leaves will collapse.

mark me please

Answer 2

When a positively charged object is brought near the electroscope, it causes the leaves to have a positive charge, and the leaves repel each other.

Explanation:

• whilst the positively charged electroscope is touched, its rate will become grounded (or neutralized).
• Being definitely charged, the electroscope attracts a few electrons from the undertaking material (in this example, someone).
• The negatively charged electrons input the electroscope and neutralize the high-quality charge.
• The leaves will flow towards every different. if you deliver an advantageous object close to the electroscope, it's going to attract the electrons towards the terminal.
• The leaves will flow far away from every different.
