Questions About Physics

 Why is the electric field inside a conductor zero?

Ans:

The intensity of the electric field in a charged conductor is zero; Because in a good conductor, the charges always settle on the conductor's surface, leaving zero charges inside and resulting in zero electric fields.

Where does charge go in a conductor?

Ans:

Any excess charge lives on the surface of the conductor. The electric field is zero within the solid part of the conductor. The electric field at the surface of the conductor is perpendicular to the surface. Charge accumulates, and the field is strongest, on pointy parts of the conductor.

In which area is the surface charge density maximum on a conductor?

Ans:

Surface charge density is maximum at sharp edges and points. The reason is that, at sharp edges and points, charges get accumulated in order to maintain an equipotential nature. It means the voltage or the potential is equal across the surface of the conductor. This happens only if the charges concentrate.
