A negatively charged rod is brought near a neutral electroscope, what happens in the electroscope?

• Electrons move from the plate to the vein to make the vein negatively charged.

• Protons move from the plate to the vein to make the vein positively charged.

• Electrons move from the vein to the plate to make the vein positively charged.

• Protons move from the vein to the plate to make the vein negatively charged.

A negatively charged rod touches the plate of a neutral electroscope, what happens in the electroscope?

• Electrons move from the rod to the plate and to the vein to make the vein negatively charged.

• Protons move from the rod to the plate and to the vein to make the vein negatively charged.

• Electrons move from the vein to the plate and to the rod to make the vein positively charged.

• Protons move from the vein to the plate and to the rod to make the vein negatively charged.
