Question

tisa makes a diagram to organize her notes about charging objects. which statement should she place in the region marked x? friction conduction electrons move between objects. the objects do not touch. the objects develop opposite charges. the objects have the same charge.

Explanation:

• Electrons move between objects: In both charging by friction and conduction, electrons are transferred. In friction, electrons move from one object to another due to rubbing. In conduction, electrons move when objects are in contact.
• The objects do not touch: This is only for charging by induction, not for friction (which requires rubbing/touching) or conduction (which requires contact).
• The objects develop opposite charges: In charging by friction, objects get opposite charges. But in conduction, if a charged object conducts to a neutral one, the neutral one gets the same charge as the initially charged object (e.g., a positively charged rod touches a neutral sphere, the sphere becomes positive).
• The objects have the same charge: This is not a commonality. In friction, charges are opposite. In conduction, if a charged and a neutral object are involved, the neutral one takes the charge of the charged object (but if two charged objects of same sign conduct, they remain same - but this is not a general commonality like electron transfer).

Answer:

Electrons move between objects.
