Question

It is said that any charge given to a conductor comes to its surface. Should all the protons come to the surface? Should all the electrons come to the surface? Should all the free electrons come to the surface?

Answer 1

Explanation:

• In this phenomenon, the protons will never participate as they are present inside the nuclei. It is not possible for them to interact.  
• It is the conductors’ property that when a charge is given to a conductor, all the free electrons come to the surface.
• For all the electrical phenomenon, the free electrons are responsible. When the conductor is of a negative charge, then the electrons move to the conductor surface.
• When the conductor is of positive charge, then the electrons repel from the surface, which will result in a positive charge on the surface.
