Answer 2

The electroscope would discharge.

Step-by-step explanation:

The leaves of the positively charged electroscope are apart. As we known like charges repel each other. When a negatively charged object is touched with a positively charged electroscope, transfer of electrons takes place which neutralizes the positive charge. The electroscope gets discharged and the leaves come back to their original position.
