Question

When a charged object is brought near a neutral insulator, some surface charge is produced on the insukator. The process in called "Polarization", Microscopically what happens during polarization?

A. New electrons are created at the insulator's surface

B. Protons move a macroscopic (large) distance through the insulator to produce the excess charge

C. Electrons move a distance no larger than the size of an atom to produce excess charge. The atoms are slightly deformed by the force of the external charge.

D. Electrons move a macrospic (large) distance through the insulator to produce the excess charge.

Explanation / Answer

C. Electrons move a distance no larger than the size of an atom to produce excess charge. The atoms are slightly deformed by the force of the external charge.
