Question

a negatively charged electroscope has separated leaves. (a) suppose you bring a negatively charged rod close to the top of the electroscope, but not touching. how will the leaves respond? (b) how will the leaves respond if you bring a positively charged rod close to the top of the electroscope, but not touching?

Answer 1

The leaves of a negatively charged electroscope will move apart if a positively charged rod is brought close to the top of the electroscope, but not touching it.

What is an electroscope?

An early scientific tool used to find an electrical charge on a body is called an electroscope. The movement of a test object caused by the Coulomb electrostatic force is used to detect charge. An object's charge is inversely proportional to its voltage.

part a) leaves will repel. leaves will move further apart.

part b)  all the negative moves to the top to get closer to the positive leaves go back together as an excess negative move to the top.  leaves separate less.
