Electric Fields and Conductors Concepts

What is the electric field at any point inside a metal conductor in electrostatic equilibrium?

• It is always zero.

• It is constant but non-zero.

• It varies depending on the conductor's shape.

• It depends on the amount of charge on the conductor.

Where does any excess charge on a metal conductor in electrostatic equilibrium reside?

• Evenly distributed throughout its volume.

• Concentrated at its center.

• Only on its outer surface.

• Only at its sharpest points.

What is true about the electric potential at all points on and inside a metal conductor in electrostatic equilibrium?

• It is always zero.

• It is the same everywhere.

• It varies from point to point.

• It is highest at the center.

How does the electric field strength just outside a metal conductor relate to the curvature of its surface?

• It is strongest at areas with less curvature.

• It is weakest at sharper areas.

• It is strongest at sharper areas.

• It is unrelated to the surface curvature.

Where does charge tend to accumulate on a charged metal conductor with an irregular shape?

• Evenly across the entire surface.

• At flat surfaces.

• At sharp points or areas of high curvature.

• In the interior of the conductor.

When two metal conductors are connected by a metal wire and charged, what condition must be met for charge to stop moving between them?

• Their total charges must be equal.

• Their electric fields must be equal.

• Their electric potentials must be equal.

• Their charge densities must be equal.

If a small metal sphere with radius R and a large metal sphere with radius 2R are connected by a metal wire and charged, how will the total charge distribute between them?

• The small sphere will have twice the charge of the large sphere.

• The large sphere will have twice the charge of the small sphere.

• Both spheres will have an equal amount of charge.

• The small sphere will have four times the charge of the large sphere.

Considering the two connected metal spheres (radius R and 2R) from the previous question, how does the electric field strength at the surface of the small sphere compare to that at the surface of the large sphere?

• The electric field is stronger around the large sphere.

• The electric field is stronger around the small sphere.

• The electric field is equal around both spheres.

• The electric field is zero around both spheres.
