why all the charges in conductor reside on surface?
The concept of charge residing on the surface of a conductor is based on the principle of electrostatic equilibrium. This means that in a conductor, the electric field inside the material is zero, and all excess charges reside on the surface, in order to minimize repulsive forces between them.
Charge resides on the surface of a conductor because of the high mobility of electrons in a conductor. When a conductor is charged, the excess charge quickly spreads throughout the surface of the material due to the repulsive forces between electrons.
The distribution of charge on the surface of a conductor is determined by the shape of the conductor and the location of any external charges. The excess charges will distribute themselves in a way that minimizes the electric potential energy of the system.
When an external charge is brought near a charged conductor, the excess charges on the surface of the conductor will redistribute themselves in order to maintain electrostatic equilibrium. This can result in induced charges on the surface of the conductor, attracting or repelling the external charge.
Yes, the charge distribution on a conductor's surface can be changed by applying an external electric field. This will cause the excess charges to move and redistribute themselves on the surface of the conductor. However, once the external field is removed, the excess charges will again redistribute to maintain electrostatic equilibrium.
