Explanation:
Surface charge density:
- The electric field at the surface of a charged conductor is proportional to the surface charge density.
- Surface charge density is the amount of charge per unit area on the surface of a conductor.
- The electric field lines originate from positive charges and terminate on negative charges.
- Therefore, the electric field at the surface of a charged conductor is directly related to the amount of charge present on the surface.
Volume of the sphere:
- The volume of the sphere does not directly affect the electric field at the surface of a charged conductor.
- The electric field is dependent on the charge distribution on the surface, not the volume of the conductor.
Volume charge density:
- Volume charge density refers to the amount of charge per unit volume within a conductor.
- The electric field inside a conductor is affected by the volume charge density, not the electric field at the surface.
Area of the sphere:
- The area of the sphere is related to the surface area of the conductor, which is directly proportional to the surface charge density.
- However, the electric field at the surface is directly dependent on the surface charge density, not the total area of the sphere.
Therefore, the correct answer is that the electric field at the surface of a charged conductor is proportional to the surface charge density.
