The direction a negative test charge would move.

The direction a positive test charge would move.

The magnitude of the electric field.

The path of an electron.

The strength is indicated by the color of the field lines.

The strength is indicated by the spacing between the field lines; closer lines mean a stronger field.

The strength is indicated by the length of the field lines.

The strength is uniform regardless of the spacing.

Electrons are tightly bound and cannot move freely.

Electrons can move freely throughout the material.

Electrons move only in one direction.

Electrons are not present in the material.

Uniformly throughout the volume of the sphere.

Uniformly on the surface of the sphere.

Mostly in the center of the sphere.

Mostly on the bottom of the sphere.

The electric field is always zero inside both conductors and insulators.

The electric field is zero inside a conductor in electrostatic equilibrium, but it can be non-zero inside an insulator.

The electric field is always non-zero inside a conductor, but it is always zero inside an insulator.

The electric field is the same inside both materials.

The electric field inside remains the same as the external field.

The electric field inside becomes stronger than the external field.

The electric field inside becomes zero due to charge redistribution on the conductor's surface.

The electric field inside oscillates with time.
