when some charge given to a material spreads on the entire surface, it is a conductor. how? explain

Electric field inside a conductor is zero. We can not have net charge in a given volume inside the conductor
because electric field is zero inside conductor , Hence all the charges given externally to the conductor resides only on surface.
If charges accumulate at one place on a surface of conductor, this will give electric field inside conductor.
Hence in order to get zero electric field inside conductor , the charge on the surface spread over the surface uniformly.
From energy point of view, Chrage on the conductor will seek a configuration that minimizes its potential energy.,
Electrostatic energy of a solid object with specified shape and charge is minimum when charge is spread over surface.

- if we rubbed comb in hair and then we brought near paper then we see they get attract each other ,so in that case comb is negative or positive charge ?
- charge of electron is negative but in solving numericals why we take charge of the electron POSITIVE?????
- Pick the true statements about electric field lines It provides information about the direction of the electric field Electric field lines provide information about the type of charge Electric field lines provide information about the field strength All of the above
- a charged sheet having surface charge density 15 ^-4 cm^-2 is given. find charge on sheet if it's surface area is 1000 cm^ 2
