Which of the following statements about charging by conduction is FALSE? Check all that apply... - A negatively-charged rabbit fur and positively-charged human skin will result when rubbed together. In contrast, a positively-charged rabbit fur and negatively-charged human hair will result when rubbed together. Note that rubbing a metal pipe with rabbit fur can also transfer electrons, but these electrons will immediately pass through the conductor to the experimenter and then to the Earth.

- In charging by conduction, charging by contact differs from charging by friction where only one physical contact point is needed instead of the entire rubbing surface, the neutral uncharged objects can be either insulators or conductors, one object is already charged instead of beginning with two neutral objects, and both objects have the same charge afterward instead of having opposite charges.

- Charging by contact occurs when a negatively-charged ebonite rod touches a neutral object to remove electrons from the neutral object so that it becomes negatively-charged or occurs when a positively-charged glass rod touches a neutral object to transfer electrons to the neutral object so that it becomes positively-charged.

- Charging by friction occurs when two, different, neutral, solid or liquid, insulators such as silk and wool are rubbed together where silk has a weaker hold on electrons will lose electrons and become positively-charged while wool has a stronger hold on electrons will gain electrons and become negatively-charged.
According to the electrostatic (triboelectric) series, after rubbing their bodies together from greeting each other, the cat fur on the grey kitten becomes positively-charged while the cat fur on the orange kitten is negatively-charged. A neutral rubber balloon suspended from a ceiling by an insulating string will attract the cat fur of the grey kitten, but repel the cat fur of the orange kitten.
