Electric Field Behavior in Conductors

What happens to a single charge placed on a neutral metal sphere?

• It creates an electric field inside the sphere.

• It can move anywhere on the sphere.

• It moves to the center of the sphere.

• It stays in one place.

When two charges are placed on a metal sphere, how do they behave?

• They create a magnetic field.

• They move as far apart as possible.

• They move to the center of the sphere.

• They attract each other.

What is the effect of adding more charges to a metal sphere?

• The charges move to the center.

• The charges attract each other.

• The charges distribute evenly on the surface.

• The charges create a magnetic field.

Why is there no electric field inside a conductor?

• Because the conductor is insulated.

• Because the charges are stationary.

• Because the charges cancel each other out.

• Because the charges move to the surface.

How do charge carriers in a conductor respond to an external electric field?

• They move to the center of the conductor.

• They create a magnetic field.

• They remain stationary.

• They move to the surface to cancel the field.

What happens to the positive charges in a conductor when placed in an external electric field?

• They remain stationary.

• They move to the center of the conductor.

• They move in the same direction as the field.

• They move in the opposite direction of the field.

How do negative charges in a conductor react to an external electric field?

• They move in the same direction as the field.

• They move in the opposite direction of the field.

• They remain stationary.

• They move to the center of the conductor.

What is the role of a Van de Graaff generator in the demonstration?

• To create a magnetic field.

• To generate a positive charge.

• To insulate the metal sphere.

• To neutralize the charges.

What is the main point demonstrated by the Van de Graaff generator?

• Conductors can cancel external electric fields.

• Conductors can generate magnetic fields.

• Conductors can create electric fields.

• Conductors can hold a charge indefinitely.

What is the behavior of a non-conductor in an electric field, as shown in the demonstration?

• It generates its own electric field.

• It does not allow charge movement.

• It behaves the same as a conductor.

• It cancels the external electric field.
