closer together.

An electroscope is charged positively as indicated by foil leaves that stand apart. As a negative charge is brought close to the electroscope, the leaves become

positive ion.

If electrons are stripped from an atom it becomes a

charge polarization.

If you rub an inflated balloon against your hair and place the balloon against the wall it will stick to the wall, illustrating

absence of electric resistance.

Superconductors are noted for their

specific large number of electrons.

The unit of electric charge, the coulomb, is the charge on a

can be neither created nor destroyed.

To say that electric charge is conserved is to say that electric charge

4 N.

Two charges that are separated by one meter exert 1-N forces on each other. If the magnitude of each charge is doubled, the force on each charge is

quadruples.

When the distance between two charges is halved, the electrical force between them

neutron

Which of these does NOT have an electrical charge?
