A positively charged rod is brought near a metal electroscope that is initially uncharged. As shown in the figure, the rod does not touch the electroscope. There is no charge transfer between the electroscope and rod, but the leaves of the electroscope move apart from each other when the rod is brought near the top of the electroscope. Which one of the following choices is the best explanation for this phenomenon? + + + + + + electroscope O Protons are repelled by the rod into the leaves of the electroscope. Electrons are attracted out of the leaves of the electroscope toward the rod. Protons are repelled into the leaves of the electroscope and electrons are attracted out of the leaves of the electroscope. O Positively charged electrons are repelled by the rod into the leaves of the electroscope. O Positively charged electrons are repelled into the leaves of the electroscope and regular electrons are attracted out of the leaves of the electroscope.

An eletrostatic paint sprayer consists of a charged metal sphere. Charged paint droplets (the sign the same as the metal sphere) are shot towards the metal sphere using a paint gun. The paint droplets repel and move towards a grounded object that needs to be painted. In the figure below, an electrostatic paint sprayer has a 0.25 m diameter metal sphere at a potential Vsphere of 23 kV that repels paint droplets onto a grounded wall. a) What charge is on the sphere? b) What charge must a 0.14 mg drop of paint have to arrive at the object with a speed of 12 ms?
