Question

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

Answer 1

Answer:

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.
