6.2 The Transfer of Static Electric Charges

What happens to an originally neutral object when it is charged by contact?

• It gains the same type of charge as the charged object that touched it.

• It gains the opposite charge to the charged object.

• It remains neutral.

• It becomes grounded.

What is an electroscope?

• A device that grounds charged objects.

• A device that measures the weight of charged objects.

• An instrument that can detect static electric charges.

• An instrument that charges objects by induction.

What is the study of static electric charges called?

• Electrostatics

• Electrodynamics

• Electromagnetism

• Electroscope

What happens when an object is grounded?

• It gains more electrons from the ground.

• It loses electrons to the ground.

• Electrons are transferred between the object and the ground, making the object neutral.

• The object becomes positively charged.

What is the effect of charging by induction on a neutral object?

• It gains the same type of charge as the charged object.

• It gains the opposite charge to the charged object.

• It remains neutral.

• It becomes permanently charged.

What happens to the leaves of an electroscope when a negatively charged rod is brought near it?

• The leaves move down and the electroscope becomes positively charged.

• The leaves repel each other and the electroscope stays neutral.

• The leaves attract each other and the electroscope becomes positively charged.

• The leaves repel each other and the electroscope becomes negatively charged.

What is the process called when electrons move from a charged object to a neutral object upon contact?

• Charging by friction

• Charging by induction

• Charging by contact

• Charging by conduction

What is induction in the context of charging objects?

• The transfer of electrons through direct contact

• The movement of electrons within an object caused by a nearby charged object without direct contact

• The grounding of a charged object to make it neutral

• The transfer of electrons through friction

What happens when you bring a negatively charged balloon near a neutral wall?

• The wall becomes negatively charged.

• The wall remains neutral.

• The wall becomes positively charged.

• The balloon becomes neutral.

How can you permanently charge an object by induction?

• By touching it with a charged object

• By grounding the object after it has been induced by a charged object

• By rubbing it with a cloth

• By placing it in a strong electric field
