If a negatively-charged rod is brought close to an electroscope that is negatively charged, what will the two leaves of the electroscope do?

move closer together

move farther apart

not move at all

become positively charged

Move further apart

Explanation:

The negative charge on the rod repels the electrons on the cap thus they concentrate at the leaves causing an increase in the amount of charge at the leaves. Since like charges repel, the two leaves of the electroscope move further apart.
