Answer 1

a)when we touches the top of electroscope with positively charged object then their leaves spread apart
b)when we touch an electroscope with negatively charged object then the leaf of electroscope will also spread apart

Answer 2

Answer:

(a) When a positively charged electroscope is touched, electrons enter the electroscope from the ground. Being positively charged, the electroscope attracts some electrons from the conducting material. The negatively charged electrons enter the electroscope and neutralize the positive charge.

(b) When a negatively charged object is brought near an electroscope the charge will induce a positive charge on the leaves.
