If you place a large number of electrons in one small spot on a conductor, they immediately redistribute themselves on the surface because they repel one another. What happens if you place a large number of electron in one small are on the surface of an insulator?

O They immediately redistribute themselves on the surface of the insulator because they repel one another.

O They stay in the area in which they were initially deposited for a relatively long time because they are not free to move about the insulator.

O They immediately redistribute themselves throughout the entire volume of the insulator because they repel one another.

They stay in the area in which they were initially deposited for a relatively long time because they are not free to move about the insulator.

Explanation:

If we place large number of electrons in a small area of an insulating surface then the charges will remain in their place for a longer period of time because the charges do not get a path to flow despite the repulsion between them.

Insulators do not have conducting electrons free to carry the charges apart from each other whereas the metal have a sea of electrons free for the conduction of charges.
