Understanding Charging by Induction

What is the primary difference between conductors and insulators in the context of polarization?

• Insulators allow free flow of electrons, while conductors do not.

• Neither conductors nor insulators allow free flow of electrons.

• Conductors allow free flow of electrons, while insulators do not.

• Both conductors and insulators allow free flow of electrons.

In the process of charging by induction with a positive balloon, what happens to the electrons in the neutral sphere?

• They are attracted to the balloon.

• They are repelled from the balloon.

• They remain stationary.

• They are absorbed by the balloon.

During the charging step with a positive balloon, what role does the hand play?

• It absorbs the positive charges.

• It repels electrons from the sphere.

• It neutralizes the positive excess charge.

• It provides additional positive charges.

When using a negatively charged balloon, what happens to the electrons in the neutral sphere?

• They remain stationary.

• They are absorbed by the balloon.

• They are attracted to the balloon.

• They are repelled to the opposite side.

In the electrophorus lab experiment, what is the result of the aluminum pie tin losing electrons?

• It gains additional electrons.

• It remains neutral.

• It becomes positively charged.

• It becomes negatively charged.

What is the role of the ground in the electrophorus lab experiment?

• It provides additional electrons.

• It absorbs electrons from the pie tin.

• It repels the electrons in the pie tin.

• It has no role in the experiment.

In the pop can experiment, what happens when a positively charged balloon is brought near the cans?

• Electrons move from can Y to can X.

• Electrons move from can X to can Y.

• Electrons are absorbed by the balloon.

• Electrons remain stationary.

What is the result of separating the pop cans after induction charging with a positive balloon?

• Can X is positively charged, and Can Y is negatively charged.

• Both cans become positively charged.

• Both cans become negatively charged.

• Can X is negatively charged, and Can Y is positively charged.

How does the ground function when electrons leave object X into the hand?

• As a repeller of electrons.

• As a neutralizer of charges.

• As a sink for electrons.

• As a source of electrons.

What is the best type of ground for induction charging experiments?

• The Earth or a large conductive object.

• A large insulating object.

• A small metal object.

• A plastic surface.
