Question

What happens when a positively charged body is brought

a. in contact with the metal disc of a negatively charged electroscope?

b. in contact with the disc of uncharged electroscope?​

Answer 1

Step-by-step explanation:

When the negatively charged body is brought in contact with disc, the strips of electroscope diverges, this shows that the charge on electroscope is negative. So, if we brought the positively charged body in contact with disc, the divergence of the strips decreases.
